Where should I start looking for an online gene library?
Is there an online library that includes all known genes in stored in their nucleotide form of all living organisms? I'm presuming that such a database doesn't exist. So to kick of my search, how can I find a gene amongst all the other databases? Where is a good place to start looking for information about my gene given that it is a well studied sequence? The issue is that I have been provided with the sequence, but I just don't know what organism the sequence belongs to or what it codes for.
