NAME

FAST::Bio::SeqFeature::Gene::ExonI - Interface for a feature representing an exon

SYNOPSIS

See documentation of methods.

DESCRIPTION

A feature representing an exon. An exon in this definition is transcribed and at least for one particular transcript not spliced out of the pre-mRNA. However, it does not necessarily code for amino acid.

FEEDBACK

Mailing Lists

User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to one of the Bioperl mailing lists. Your participation is much appreciated.

Support

Please direct usage questions or support issues to the mailing list:

bioperl-l@bioperl.org

rather than to the module maintainer directly. Many experienced and reponsive experts will be able look at the problem and quickly address it. Please include a thorough description of the problem with code and data examples if at all possible.

APPENDIX

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _

is_coding

Title   : is_coding
Usage   : if($exon->is_coding()) {
                  # do something
          }
Function: Whether or not the exon codes for amino acid.
Returns : TRUE if the object represents a feature translated into protein,
          and FALSE otherwise.
Args    : 

cds

Title   : cds()
Usage   : $cds = $exon->cds();
Function: Get the coding sequence of the exon as a sequence object.

          The returned sequence object must be in frame 0, i.e., the first
          base starts a codon.

          An implementation may return undef, indicating that a coding
          sequence does not exist, e.g. for a UTR (untranslated region).

Returns : A L<FAST::Bio::PrimarySeqI> implementing object.
Args    :
