Hi Perl Monks, I need to print the sequence starting with ATG and ending with TGA,TAA,TAG. My code prints the two sets of sequence ending with TAA only, I am having trouble printing sequence ending with TGA as well, as there is TGA codon in the original sequence. 

#!/usr/bin/perl
#FindCoding.pl
use warnings;
use strict;
use diagnostics;
my $sequence = 'AATGGTTTCTCCCATCTCTCCATCGGCATAAAAATACAGAATGATCTAACGAA'
+;
while ($sequence =~ /(ATG.*?(?:TAG|TAA|TGA))/g){
print "$1\n";
}

The output is: ATGGTTTCTCCCATCTCTCCATCGGCATAA and ATGATCTAA However I am looking for sequence ending with TGA codon as well.
