Q: Hello, my name is Abby. I watched your NOVA affairs and was aflame to apprehend that one day scientists ability be able to accomplish a real, active creature. If this happens, would it be accessible to accomplish a dragon? Abigail Harper (age 11), San Ramon, California

David Deamer: Hi Abigail,

I adulation the abstraction of authoritative a dragon! But flying, fire-breathing dragons are best acceptable mythical, rather than absolute animals, so I’m not abiding how we would architecture a dragon. Addition botheration is that we still don’t apperceive for abiding how to accomplish a simple little bacterial cell. I’m abashed that authoritative a dragon is far in the future.

Q: My catechism has to do with irreducible complexity, and ultimately with the able architecture vs. accustomed change debate.

The botheration is this: Coded in all DNA are the instructions to body the enzymes that acquiesce the DNA to carbon itself; accordingly it’s difficult not to crave the acceptance that the aboriginal “proto-DNA” molecules accumulated themselves with this self-replicating accouterment already absolutely in place—otherwise how would the aboriginal DNA acquire broadcast itself?

How do biochemists and geneticists annual for this credible “chicken-or-egg first” quandary? And what affirmation do they adduce to aback up this accounting? Finally, ability there abide accustomed environments on Earth area self-replicating molecules or acutely simple forms of activity are spontaneously arising now? Robert Shaw, Oklahoma City, Oklahoma

Deamer: Dear Rob,

You accompany up some absorbing and important questions. They can’t be answered yet, but we are authoritative a little progress. Your antecedent point assumes that a DNA-RNA-protein apple sprang into actuality spontaneously, and this seems unlikely, as you noted. One way out of the brain-teaser is to accede that simpler forms of abiogenetic advice and catalysts were apparatus of archaic cellular life. For instance, assertive kinds of RNA are alleged ribozymes because they can act as catalysts. They can additionally backpack abiogenetic advice in their abject sequence, and this has led to the advancement that an RNA apple came first, in which RNA served both as a agitator and as a abiogenetic material. David Bartel and his co-workers acquire in actuality apparent a ribozyme that can archetype a arrangement of 14 nucleotides. If we can anytime acquisition a ribozyme that is able to archetype itself entirely, this would breach the chicken-egg problem.

In attention to your additional catechism about whether simple forms of activity may still be appearing, apparently not, because they would bound be devoured by added avant-garde activity that inhabits the Earth today. However, I anticipate we can apprentice article by abacus simple chemicals to geothermal environments and attractive for both degradative and constructed reactions. In my analysis accurate by the NASA Astrobiology Institute, we are accustomed out such abstracts in Kamchatka, Iceland and best afresh Mt. Lassen, California, as apparent in the NOVA program.

You additionally mentioned the able architecture (ID) question. Aloof aftermost anniversary I alternate in a appointment with Paul Nelson and Robert D’Agostino, both proponents of ID. My capital point adjoin teaching ID as an addition to change is that ID does not authorize as science. It is an assessment based on religious convictions, not on absolute evidence, nor can it be activated in the accepted way.

Q: Supposing the agreement [to actualize bogus life] succeeds; to what admeasurement will the actuality that our ability is amenable for the conception of activity explain the origins of activity on Earth? Everything considered, wouldn’t this be like architecture a circuitous apparatus from its genitalia with an apprenticeship manual, or is there added to it? George Marvin, Mexico

Deamer: Dear George,

You are appropriate on target. The aboriginal kinds of bogus activity in the class will use apparatus like ribosomes that we don’t yet apperceive how to accomplish from simpler materials. In added words, it will be an engineering admission application a apparatus kit and apprenticeship chiral provided by active organisms. But we are additionally attractive for self-assembly processes that can advance to structures announcement assertive backdrop of life. A simple archetype is the self-assembly of lipids into cell-sized bleary vesicles. We did not apperceive this was accessible until it was aboriginal approved in the 1960s. We are now aggravating to acquisition means in which self-assembly processes can accomplish polymers of life. For instance, Jim Ferris and his co-workers acquire apparent that nucleotides can accumulate on adobe mineral surfaces in such a way that abbreviate polymers of RNA are produced.

Q: I was activity to activate a science fair activity apropos this subject. It involves the bogus amalgam of activity in a apish aboriginal Earth ambiance and added planets. It would be modeled like the Miller-Urey Agent of Activity experiment. If you acquire any suggestions about how to go about accomplishing my project, it would be abundantly appreciated. Thank you for demography the time to apprehend this. Andrew, Texas

Deamer: Hi Andrew,

This would be appealing complicated, because you will crave a antecedent of hydrogen gas, methane, and ammonia, as able-bodied as a aerial voltage electrical atom to drive the reaction. You would allegation to be actual careful, aback hydrogen and methane are atomic beneath assertive conditions!

I can advance article simpler, but it depends on what accessories you acquire to assignment with. Do you acquire admission to a microscope and agenda camera? If so you ability try authoritative lipid vesicles from lecithin that you can buy at a bloom aliment store. For cellular activity to begin, some array of corpuscle film is required, and there are absolutely a few abstracts you can do with lecithin that are accompanying to the agent of life. You can use the agenda camera to booty photos appropriate through your microscope. If you would like to try this, amuse appointment my Web folio at the University of California, Santa Cruz, and accelerate me an email.

Q: What would you adumbrate to be the ancient antecedent of activity for the aboriginal life-forms; chemosynthetic (energy from asleep molecules) or heterotrophic (energy from amoebic molecules)? Dr. James Backer, Daytona Beach Community College, Daytona Beach, Florida

Deamer: Dear Dr. Backer,

Good question, and I acquire accustomed this some anticipation over the years. Chemosynthetic activity is accessible about everywhere, and avant-garde microbial activity makes acceptable use of it alike in environments such as hydrothermal vents. However, application this activity requires a film that can advance a chemiosmotic acclivity of protons, so the aboriginal beef would allegation a antecedent of lipid-like molecules as able-bodied as an electron carriage action that can pump protons. Heterotrophic activity may acquire additionally been accessible if we acquire that amoebic compounds were present on the aboriginal Earth. The catechism is how to abduction the actinic activity and accumulate it in one place, so afresh a film alcove is needed. We should additionally accede ablaze energy, which requires both a film and colorant molecules for it to be captured. I don’t anticipate we apperceive abundant to accomplish an a best yet, so all three activity sources should be investigated.

[Editor’s note: Below are two accompanying questions that David Deamer answered in one response.]

Q: Ascertain ‘life.’ Aback we assuredly appointment ‘it’ elsewhere, how can we be abiding ‘it’ is alive? A.C. Clarke wrote of a abroad planet with active crystals that took a thousand years to anatomy a thought. Is that clear alive? And how will we apperceive if ‘it’ is ‘real’, or Memorex, i.e., artificial? Rick Freeman, Louisville, Kentucky

Q: 1.How does one analyze amid activity and non-life?

2.What are the basal requisites for life? David Greenberg, Cincinnati, Ohio

Deamer: Hi Rick and David,

You are allurement a catechism that abounding scientists are additionally cerebration about. There doesn’t assume to be an accessible acknowledgment that satisfies everyone. Activity is a actual circuitous phenomenon, so a analogue allegation reflect the complexity. I approved to do this for the aboriginal cellular life, and I came up with the following, which is added a description than a definition:

[Editor’s Note: The catechism of what defines activity is additionally addressed, in a animated way, in Let’s Accomplish a Microbe!]

Q: Does analysis such as this affect the development of technology not accompanying to creating constructed life? I am thinking, for instance, of how artful the biological mechanisms in the rods and cones of an amoebic eye could advice advance bigger cameras or whatnot. Jon Kopp, Lakehurst, New Jersey

Deamer: Dear Jon,

Yes, basal analysis generally leads to abrupt discoveries that acquire applied applications, as you mentioned above. A acceptable archetype is the analysis of semiconductors by addition accomplishing basal analysis in physics. Who would acquire estimated that this would advance to transistors, again computer chips and a abundance dollar industry? In my lab, we activate that a protein alleged hemolysin could carriage DNA beyond lipid bilayer membranes, and that we could ascertain anniversary DNA atom by a change of ionic current. We are now aggravating to accomplish an bogus adaptation of hemolysin that can arrangement DNA at bags of bases per second.

Q: Are there any added ‘duplicating’ molecules on Earth that are not RNA or DNA? Are there added accepted ‘duplicating’ molecules from the archaic Earth? Anonymous, Florida State University, Tallahassee, Florida

Deamer: RNA and DNA are the alone compounds we apperceive of that acquire commutual abject bond which allows them to replicate.

Q: It was said in the affairs that the time aback activity will be acquired in a lab is over the border or aloof about the corner. Aloof how continued will it be, really, till we absolutely see this artificially acquired life? Jason Kwon, Indianapolis, Indiana

Deamer: Hi Jason,

The acknowledgment depends on how we ascertain bogus life. If we booty afar a bacterial corpuscle and put it aback calm into a simplified organism, that ability appear in the aing ten years. But if you appetite us to alpha from scratch, application as starting actual chemicals like amino acids, nucleotides, phosphate, sugars, lipids and so on, that’s a continued way off. The alone affair that makes me anticipate it’s not an absurd assignment is that activity seems to acquire started this way about 4 billion years ago on the aboriginal Earth. If we can bigger acquire how this happened, it ability about-face out to be easier than we anticipate for a actual simple anatomy of activity to begin.

Q: What are the abstracts you allegation to accomplish DNA? Kaitlin Larese (age 5), Albuquerque, New Mexico

Deamer: Hi Kaitlin,

Wow! What a abundant catechism from a five-year-old! You allegation phosphate, a affectionate of amoroso alleged deoxyribose, and four chemicals alleged bases that acquire the belletrist A, T, G, and C. If you articulation these calm like chaplet on a string, you get DNA.

Q: I like the abstraction of application science to try and explain activity on Earth, but do you anytime anticipate that all the analysis ability go too far one day? I’m anxious that in the approaching scientists ability apprentice too abundant about how to actualize activity and agitated the accustomed processes that occur. Do you anytime anticipate that attributes should aloof booty its advance while we aloof abstraction it, but not try and adapt it or try and become as able as nature? Julie Groff, West Chester, Pennsylvania

Deamer: Dear Julie,

You acquire asked a actual anxious catechism that avalanche into a new acreage alleged bioethics. Let me say aboriginal that I don’t anticipate bogus activity is abundant of a threat, alike admitting science fiction writers adulation to alarm us this way. The acumen is that we can already architect absolute forms of bacilli and bacilli so that they are actual dangerous, so why bother authoritative bogus life? The added allotment of your catechism is whether we should let attributes booty its course, abstraction it but not try to ascendancy it. I alone achievement that the animal chase will apprentice to animate on the Earth afterwards damaging the ambiance any added than we acquire already. On the added hand, if we let attributes booty its course, we would still acquire smallpox and polio bacilli killing people. So it seems to me that we do allegation to ascendancy assertive aspects of nature, but we should additionally acquire that we are allotment of nature, and that we allegation apprentice to booty affliction of our accustomed world.

Q: Aback they were aggravating to get bogus activity started by abacus chemicals to altitude anticipation to abide on the aboriginal Earth, did they anticipate about the achievability of abacus a lightning strike? This allegation could add article that could be missing due to the accessible actinic changes and the activity created by the lightning. Aloof a thought. Patrick, Macomb, Michigan

Deamer: Hi Patrick,

That’s a actual acceptable thought! In fact, aback Stanley Miller did his acclaimed agreement in 1953, he activate that amino acids could be actinic by sparking a gas admixture with bogus lightning. So you are on the appropriate track.

Q: Aboriginal I appetite to say that I adulation UCSC, and I am applying to be a apprentice there aing year as a bio major. I was aloof apprehensive if there is a specific animal that the constructed activity is activity to be modeled after? Are advisers application pieces of addition organism’s abiogenetic actual to cipher for capital proteins? Shane (high academy senior), Grand Junction, Colorado

Deamer: Hi Shane,

I anticipate you will adore actuality a apprentice at UCSC—please appear by to say accost aback you access aing year. To acknowledgment your questions, my assumption is that we will use bacilli as a archetypal for simple cells. The aboriginal footfall will be to breach afar bacterial beef and again try to put the pieces aback together. One such agreement was afresh performed by Vincent Noireaux and Albert Libchaber at Rockefeller University, and their cardboard was appear aftermost year in PNAS [Proceedings of the National Academy of Sciences]. They bankrupt up E. coli bacterial cells, again captured ribosomes and added atomic apparatus in bogus lipid vesicles forth with agent RNA appropriate for the amalgam of two specific proteins. Their constructed beef “lived” for up to four canicule by demography up nutrients from the advance average and bearing abundant quantities of blooming beaming protein and hemolysin. The constructed beef were not absolutely alive, however, aback they could not abound or reproduce.

Q: Will it eventually be accessible to actualize absolutely aboriginal activity from blemish for specific purposes? How about a carpeting charwoman abrasion or a huge, beef-shedding creature? Jesse Fagan, Colorado State University, Fort Collins, Colorado

Deamer: Hi Jesse,

This achievability is a long, continued way into the future, if ever. But we can do a few things that are abundant simpler. For instance, bogus genes acquire been amid into bacilli with the aftereffect that they produced admired proteins like insulin and advance hormone. And the gene for a beaming protein has been amid into goldfish to aftermath “GloFish” that you can buy over the Internet.
