5. READSEQ is a very useful utility for converting among sequence formats. Read through the online help file before continuing.
  1. Retrieve the mRNA sequence of the yeast SNF2 gene from GenBank (the accession number is YSCSNF2A, but try using other fields).
  2. Now go to a Web-based READSEQ conversion page and copy and paste the GenBank sequence into the sequence input box and choose Pearson/FASTA format as the output format. Click Perform Conversion and a new box will appear with the sequence in FASTA format. Copy and paste the sequence into the text editor and save as a file called snf2mRNA.seq on your computer.
