Bio::SeqFeature::Gene::ExonI - Interface for a feature representing an exon See documentation of methods. 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.

Reporting Bugs
Report bugs to the Bioperl bug tracking system to help us keep track the bugs and their resolution. Bug reports can be submitted via email or the web: bioperl-bugs@bio.perl.org http://bio.perl.org/bioperl-bugs/ Email hlapp@gmx.net Describe contact details here 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 Bio::PrimarySeqI implementing object. Args :
