Name of the allele for the given gene. All gene-related features (exon, CDS etc) for a given gene should share the same Allele qualifier value; the Allele qualifier value must, by definition, be different from the Gene qualifier value; when used with the variation feature key, the Allele qualifier value should be that of the variant.

Gets the key for this item. These are not necessarily unique within a list, which is why this is a property of an object to be included in a list, rather than omitting this as a property and using a dictionary instead of a list.

A label used to permanently tag a feature.

Gets the location of this feature in the sequence. This may also refers to other genbank files. For example, join(100..200,J00194.1:1..150) In this example location specifies joining of bases from 100 to 200 from the sequence in which this location data present and bases from 1 to 150 from the sequence who's accession number is J00194.1.

A submitter-supplied, systematic, stable identifier for a gene and its associated features, used for tracking purposes.

Any comment or additional information.

A number to indicate the order of genetic elements (e.g., exons or introns) in the 5' to 3' direction.

Feature tag assigned for tracking purposes.

Name of the product associated with the feature, e.g. the mRNA of an mRNA feature, the polypeptide of a CDS, the mature peptide of a mat_peptide, etc.

Indicates that this feature is a non-functional version of the element named by the feature key.

Gets the dictionary of attributes.

Accepted standard name for this feature.
