I'm sure they could use the P4 DNA sequencing biological teleporters on Mars. If you don't mind the earth-shattering kaboom.

If? There's definitely going to be life on Mars. The only question is how evolved. Probably really basic, but there might even be tiny insect like things living underground, or even worm-like. There really isn't another current explanation for the amount of methane that goes into the atmosphere, then subsequently gets used up much quicker than it's 300 year dissipation rate, based on the seasonal change. Add to this that even parts of the surface heat up to as warm as Canada, and that we know for a fact that there used to be flowing water on the surface, and may be water under the surface, there really isn't any doubt. When Curiosity comes back next week saying that the building blocks exist in the soil, that should end the speculation and start the life searching missions.

It's common in all life as we know it on the planet, which is very diverse. And based on our proximity to Mars, and similar composition, it seems the most likely. Also, it's the only way we know how to identify life, so what other means would we have of looking for it? Can't really look for something when we don't know what to look for.

Aww, TFA assumes there will be DNA in alien life forms.

What if DNA evolved on earth and alien life forms have an entirely different method for transferring information?

What if they don't have genetics?

What if they don't have cells?

They don't and we can't - however, generally speaking there aren't too many elements that could potentially act as the foundation for life (carbon, maybe silicon I'm sure there are a few others) and so far all life we've found is based either on RNA or DNA so we have to start from the assumption that that's what we're looking for.

One of the interesting questions is if there is life on mars, does it use left handed or right handed amino acids? Some argue the inconclusive viking lander life test results can be explained by right handed amino acids. It would be interesting to see what sort of protiens result from a right handed biology.

THIS

DNA and RNA are made from sugar, a phosphate, and a base. Any chemist could suggest ways that life could be based on silicon, and many could suggest ways based on Boron and Sulphur. This happens after they look over their shoulder to see oif any colleagues are around.

There are also some very interesting hypotheses about possible inter-planetary contamination. I seem to remember reading about spores being found in our upper stratosphere floating on wind currents. There were a few people that even claimed that under the right conditions, some of these spores could be launched outside the atmosphere.

It sounded far-fetched to me, but now I'm going to have to do some googling.

This was enlightening, thank you for bringing it to my attention. At first I thought it was an elaborate troll when you mentioned left and right handed amino acids, haha, but upon further reading I realize I didn't pay enough attention in biology class. =)

And carbon has a this cute little thing that it does when you catch it in a lie. It really tightens up under pressure and you can see right through it.

Maybe. But AFAIK the smart money's still on carbon, at least if you're looking for anything resembling life as we know it (i.e. no sentient nebulae). That's not to say it would have the same molecular structures as Earthly life, so veive's concern about Martian life not having DNA or RNA to sequence is still valid.

TFA is assuming Earth and Mars were seeded at some point(s) in their histories. I believe comets are the most popular vehicle in this theory.

Except for that whole pesky Si02 really really likes to be a solid. Oh and don't forget that silanes (the Si version of alkanes) like to explode. Si-H bonds have what 1/6th the strength of C-H bonds so that's is really gonna bend your carbohydrate, lipid, DNA and amino acid stability. Then there's the inability for long chains SiH(x) molecules so say goodbye to cyclic Silicone analogues of sugars, which means no lipids, DNA or life really.

It is one of the closest extra solar stars to earth and used in scifi as "that place that's mindblowingly far away but close enough we could explore". 4th closest. I think. Alpha Centauri and something else then Wolf 359.

The DNA sequence -- assuming it uses DNA -- would be gibberish as a life would undoubtedly have a different genetic code* as the odds are astronomically against the same genetic code (or even one very similar) evolving as there just so many. Obviously this assumes Martian life is unrelated to Earth life. If life started on Mars and got transported to Earth (or the reverse) then the genetic code will be the same or very similar. To determine the genetic code will require unraveling the biochemistry of Mars life which will be a little much for a few probes. It will require a long research program.

*The genetic code in technical publications does not mean DNA sequencing as pretty much every popular article seems to think. It is basically a table. This three-"letter" sequence of DNA will code for this amino acid. (Okay the table is usually done as RNA sequence but that really does not matter for our purposes.) ATG in DNA codes for methionine.
