<p>From today, I will learn and summarize how to use Bioperl by reading a book "Bioinformatics with bioperl (Author: Young-Chang Kim)"</p>
<p>1. Change DNA sequence to RNA sequence</p>
<p>$DNASeq = 'GATACAA.......'</p>
<p>$RNASeq =~s/T/U/g;</p>
<p>=~ : binding operator tells Perl to match the pattern on the right against the string on the left</p>
<p>(http://docstore.mik.ua/orelly/perl4/lperl/ch09_03.htm)</p>
<p>s/ / / : substitution function, s is substitution operator, / is used to make a distinction</p>
<p>g : pattern modifier from start to end</p>
<p> </p>
<p>==> We can utilize the =~s/ / /g to the first homework</p>
<p>If there is a certain DNA sequence, we can change the sequence into matching amino acid sequence</p>
<p>For example, Methionine has AUG codon sequence and its template DNA sequence is 3'-TAC-5'.</p>
<p>Thus, if we change the CAT sequence into M or Met, we could find the methionine from DNA sequence.</p>
<p> Ex) $Methionine = ~s/CAT/M/g;</p>
<p>Likewise, we could derive whole amino acids from DNA sequence.</p>
