SeqRecord

• The SeqRecord object has a few additional attributes beyond the Seq object:

  • seq - The sequence itself

  • id - The primary ID used to identify the sequence - a string. In most cases this is something like an accession number

  • name - A 'common' name/id for the sequence - a string. In most cases this will be the same as the accession number, but it could also be a clone name. Analogous to the LOCUS id in a GenBank record

  • description - A human readable description or expressive name for the sequence - a string
