Since I've been receiving so many e-mail queries on the subject, I
figured I'd just post the following info for everybody to see.
The direct URL for BLAST DNA sequence searching is:
http://www.ncbi.nlm.nih.gov/Recipon/bs_seq.html
However, for first-time users, I recommend linking into this page
indirectly via NLM's HyperDoc page, available at URL:
http://www.nlm.nih.gov
There's a link on this page to NCBI (National Center for Biotechnology
Information), and the links from there on to the actual sequence
searching page ought to be obvious. This route will allow you to browse
through a lot of other great resources available from NLM and NCBI, so
you might find some other interesting things out along the way to the
BLAST page.
Have fun!
