When Nucleotides Don't Work

Occasionally BLASTing genes with just a nucleotide sequence doesn't work. This can be due to a number of reasons:

  • Lack of conservation between species
  • Incomplete genome database
  • Rearrangement of introns/exons


If, for any of these reasons, you aren't getting any hits, it might be time to make sure you're doing it right:

First - Check to make sure that your database is made correctly.
  • You should have three additional files made from the original fasta file:
