Bio::SeqFeature::Gene
ExonI
Summary
Bio::SeqFeature::Gene::ExonI - Interface for a feature representing an exon
Package variables
No package variables defined.
Included modules
Inherit
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.
Methods
Methods description
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 : |
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 : |
