Hi perlmonks... thanks so much for your wonderful help... I want to ask concerning the next lines below... This is part of the code: 
print " Description   "; 
foreach my $de ($entry->DEs->elements()) {
        print OUT join ("\n", $de->text()),"\n" ;
    }

[download]
Basically the $entry->DEs->elements() will return an array of gen description and the $de->text() will return each element of the array... The content of the array :Cytotoxin, Cardiotoxin analog,CTX III,Ctx-3,Cardiotoxin C-10 The output of the above code is: 
Description   Cytotoxin
Cardiotoxin analog 
CTX III
Ctx-3
Cardiotoxin C-10

[download]
Is there any way to make the second input till the last one in bracket such as : 
Description   Cytotoxin (Cardiotoxin analog )(CTX III)
(Ctx-3)(Cardiotoxin C-10).

[download]
Thanks so muchhh.....
