   Human Genome: Current Statistics  --  Build 31

Summary of the GenBank source sequences, the contigs, and the features annotated on the sequence based on sequence information available on November 15, 2002. Also summarizes the objects on each non-sequence-based map in the MapViewer.


These statistics are based on the assembly and annotation process documented here.

See also the current release notes.
