I was thinking about this question today. If you think there could be what do you think they would have for their genetic material DNA, RNA of something completely different. As a biologist I think this is an interesting question and would love to here your ideas on the subject.

not sure about the DNA material they would consist of, but I think its very obvious that there is infact life on other planets, im not an alien abduction nut, but there just seems too many reports of strange goings on from high ranking military and police sources to deny that we are in fact already being visited by advanced powers from other worlds and have been for some time.

Indeed, there has to be, there are far too many suns (stars), far too many galaxies and universes for there not to be. If there is not, there will be, as new galaxies are being born and dying every day.
The whole of the universes, everything you can imagine, are made up of the same materials, the same chemicals. You can find all the elements all over the place, if you had a rocket that could take you everywhere that is!
DNA? don't know. If we, and everything else, has the same chemical compounds, it stands to reason that some DNA is going to be the same. It all depends on what triggers off life, whatever DNA is there at the beginning, will grow, become more complex. So IF life starts, let's say on mars, it really depends on which elements are in the new life form, some elements will be the same as ours, so I guess some DNA will be the same too.
By the way, I was crap at the sciences, I only work on logic.

Yes I think there definitely could be. Why should life originate on Earth an not any other planet. But I don't think that it is likely there is life on any of the other planets in the solar system. There are a number of extra-solar planets that have been discovered. Perhaps we will one day be able to look there.
The DNA/RNA question is very interesting. It is likely that they would have a similarly structured molecule that is translated into proteins or the alien equivalent of proteins. It is most likely to be a double stranded molecule as they are more resistant to damage from radiation. If the alien planet has a thick atmosphere, the alien life will be better shielded from radiation and may be able to survive with a single stranded genome. If the atmosphere is very thin then they may even need a triple stranded genome.
Thinking a bit more outside the box: the aliens may not have a genome. They may unwind their proteins and duplicate them directly from the original template.

Any planet of the correct mass and a distance from it's home star that will allow life to form would likely have some form of life on it.
Most of the planets around other stars that we know of are massive bodies and the gravity that exists on them and othe local conditions would almost definitely rule out life on them.
Considering the size of the universe there must be quite a few single stars out there with a planet much like the earth at the right orbit that would engender life. The chances that one would be close enough and at the same sort of development stage as the earth so we could contact any intelligent life on them are so extreme I don't think that'll ever happen.

I think that it is insane to think that with all the other planets, there is no life on any other planet. As for the genetic material of other life forms, it may be possible that it is a DNA based genetic material. But, I don't see why it would have to be. There are a lot of other molecules that could do the trick. The question is, how do we detect life on other planets. I know some are trying to mount mass spectrometers on robots to detect signature metabolites, but that is with the assumption that martian microbial life has similar metabolites as ours.

i dont see why there couldnt be, though i doubt there is on any of the other planets in our solar system.
As for the DNA/RNA question i dont know, it ther conditions on there planet are very similar to ours perhaps they will have a similar genetic material. Though if they have found a means of existance very different to ours this may be because they have a very different genetic make up that allows it. Who knows

Considering the size of the universe, which is so vast we don't even know how large it is, I would be honestly more surprised if there wasn't life on other planets. Although in our solar system, there isnt advanced life forms, who knows about microscopic life forms? We really can make no guess at what the DNA/RNA of alien life forms would be, there is just such variety of living species on earth alone, just one planet.

Yes there is if the universe itself is 'alive with change and expansion' and that is a recurrent feature. In fact it should logically exist where planetary conditions are the same as ours in a particular galaxy, in fact if there was one the same as ours i don't think it could not exist could it?
Where there is a difference in a planets aspects to ours, like the ones in our own little galaxy, I would think that life itself as we know it would not exist, but as we don't know it, probably would be. (Its life Jim but not as we know it)!!
My theory is that we are so intellectually restricted compared to the intellect of the universe that we haven't a hope of ever understanding it. Best just to wonder at the awesomeness of it all and assume if its happened here for us, its probable the universe is bright enough to have created it elsewhere!!

I actually had a really long argument with my partner about this. i do believe there is life on other planets. millions and millions of years ago, when the big bang happened. it stopped everything here on earth, but the other planets just carried on as if nothing happened. we on the other hand had to start from scratch. i also believe that aliens and what we would have looked like if the big bang never happened.

Well, Earth has life because of our atmosphere. And our distance from the sun. Seeing how large that the universe is, there HAS to be other planets with the same properties.
If not, the organisms (or aliens) could've adapted.
