Introduction to Bioinformatics
Download two hemoglobin sequences (accession# AY885671, AY885672) from
Save the FASTA format of the sequences to a file.
Name the file hemoglobin.fasta.
(choose FASTA in the
field and click
button to save the sequence to a
Write a Perl program called Perl2a.pl which (1) reads the two sequences from the file,
(2) calculates the frequency of nucleotides fo
r each sequence and (3) prints out the
results to STDOUT.
The output should look like:
Count of A = 23;
Count of A = 34;
Download from the Genbank the sequence for Homo sapiens dopamine transporter
LC6A3) (accession #M95167) and save the FASTA format of the sequence to a file
Write a Perl program called perl2b.pl which (1) constructs an associate array for the
standard genetic code
you may find a table for the code here
translates the coding part of the sequence to obtain the protein sequence; The coding
sequence starts at the 129th base and ends at 1991; (3) outputs the FASTA format of
sulting sequence to STDOUT.
Compare your results with the sequence at Genbank.
