peer agreement (net): +3| sir2 slows down gene activity some explanation Explanation: I agree with the previous posting in that it is not a mistake, but I thought I'd just provide a little bit of explanation as you sound like you're confused about what they are saying. One of the things that Sir2 does is to 'silence' genes. Don't get confused here though, it is not the gene for Sir2 that does this, but the product of that gene (a protein). In this respect your confusion is accurate, one gene cannot slow down the activity of another. But, when Sir2 protein has been produced using the information from its gene, one of its jobs is to stop the information from many other genes being used to make their corresponding proteins. In other words, Sir2 can 'slow down' the 'activity' of other genes by 'silencing' them, or stopping them being copied to produce proteins. I hope this helps a bit. Sir2 is a fairly hot topic at the moment! All the best, Iain |
