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.

Reference to a citation listed in the entry reference field.

Database cross-reference: pointer to related information in another database.

A brief description of the nature of the experimental evidence that supports the feature identification or assignment.

Frequency of the occurrence of a feature.

Symbol of the gene corresponding to a sequence region.

Synonymous, replaced, obsolete or former gene symbol.

Genomic map position of feature.

A structured description of non-experimental evidence that supports the feature identification or assignment.

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.

mod_base; Abbreviation for a modified nucleotide base.

Any comment or additional information.

Feature tag assigned for tracking purposes.

Gets the dictionary of attributes.
