Hey! These sumptious worms might
have genetically modified! I guess we can't eat them. (too
bad!)

The Genetic Code
as used by nearly all
eukaryotic nuclear genomes
To
get a nice, handy-dandy box like this:
use the following web site:
http://www.ncbi.nlm.nih.gov/cgi-bin/BLAST/nph-newblast?Jform=0
To use this, all you have to do is paste in
your sequence (note: for PROTEINS, use "BlastP"), and then click on the
particular line of interest. In this case, the RED lines are the
best matches.
