What are the basic differences between genbank, NCBI and entrez gene? And please tell some books and webpages where I can get more about the databases .(currently I'm using Bioinformatics and functional Genomics by Pavsner)

    $\begingroup$ Unfortunately, this is not a "please hold my hand and walk me through this paper/concept/idea" site. I strongly suggest you take the tour and carefully read through the help center to learn more about the site, including what is on-topic and what is not, and how to ask a good question. Use Google to find websites, that's what it's there for. Go to the databases themselves, they all have help pages. $\endgroup$ – MattDMo Mar 8 '16 at 14:17

    $\begingroup$ are you a university student or perhaps a graduate student? there are resources to help with this sort of thing - but it depends on what your status is - but I completely agree with MattDMo, though - this site is not what you need $\endgroup$ – Vance L Albaugh Mar 8 '16 at 15:18

Genbank is a database of nucleotide sequences that are public.

NCBI stands for "National Center for Biotechnology Information" (in the US).

Entrez is NCBI's retrieval system.

You can find more information in this article

I don't know which kind of databases you are looking for, but there are hundreds of them! In this wikipedia article there are some of them.

  • $\begingroup$ This is probably what the OP was after. This answer answers the question correctly and succinctly so I'm not sure why it received a downvote other than you were setup to fail because of the off-topic question. $\endgroup$ – James Mar 9 '16 at 2:40
