To know where the UTRs are in your sequence you will need to have  
some kind of annotation associated with the sequence.  A couple of  
common sources for those annotations would be from a GenBank,  
ENSEMBL, or GFF3 - something that says there is a 3' UTR located  
between the locations 1,234 - 1,456 on your sequence.  Fasta sequence  
would normally not have that kind of information associated with it.   
You may need to rethink your source data.

You should have a look at a few of the very well written bioperl HOWTOs:


Have a look through those documents to get an idea of how to handle  
sequences and annotations with bioperl, decide which approach applies  
best to your data, and then if you have more questions about how to  
implement the details drop us a line with more specifics about your
