description: A GI number (for GenInfo Identifier, sometimes written in lower case,
  _gi_) is a simple series of digits that are assigned consecutively to each sequence
  record processed by NCBI. The GI number bears no resemblance to the Version number
  of the sequence record. Each time a sequence record is changed, it is assigned a
  new GI number.
