A while ago if I remember correctly I heard about some sort of extremophiles that lived underneath the ocean in the volcanic vents, and supposevly they have some different RNA (or was it DNA) from all the living organisms of Earth. but I cannot find any links at all...can someone help me please.
Studying redesigned genetics is a interest of mine: Peptide nucleic acids could hypothetical work at much higher temperatures then DNA/RNA, without the repulsion of the negatively charged phosphate groups it forms much stronger helix but at the price that it can dissociate/denature easily for replication purposes... unless the temperature was higher. As far as known PNA is a synthetic construct and has no natural existence in terrestrial biology.
Thats the group that is doing the research on the extremophiles they found in South Africa. You have to wait for the animation to get over and access the links to the info.
I did already, draqon wants specifics on novel genetic mechanism found in extremophiles, can you link that specifically and not the the research news server in general that might have such information. for example if you wanted a specific article on a UFO spotted at the burial of Princesses Dania I'm not going to be able to get away with just linking to the BBC's front page.
I don't think they have reached that stage yet. From the page I linked: http://www.indiana.edu/~deeplife/homepg.html They also have a podcast page here: http://podcast.iu.edu/portal/PodcastPage.aspx?podid=d6875a3d-cbe4-4b94-aca2-5874954ec2f8 edit: I found some more info: http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=161588
Glad to oblige. I don't know much about it, except what I read here and there in the news. I just remembered that IU had found them in South Africa.
Two easy things: different GC content (depend on temperature) as well as connected different codon biases.
Of course! Thats so obvious, I did not think of it!Please Register or Log in to view the hidden image!
