...working on a homework... - $honesty++.

Some sample data, outlining both matching and non-matching cases, would help - IMO, your description doesn't quite cut it for me - I'm barely a proficient programmer, I'm most certainly not a geneticist e.g. in this case, is a gene represented by a single char, a sequence of chars, or both?

That being said...

1. This: 

.
.
$text = "";
while($line = <IN>)
{
    $text .= $line;
}
.
.

is more usually (and in most cases, better) written as... 
local $/; # Ensure line-ends are ignored
$text = <IN>;
.
.

2. AFAICT i.e. subject to further details being provided, your RE appears to only capture start & end delimiters.

A user level that continues to overstate my experience :-))
