<term id="bid.1238">3-D or 3D</term>
<term id="bid.1722">Accession number</term>
<p>An Accession number is a unique identifier given 
to a sequence when it is submitted to one of the DNA 
repositories (GenBank, EMBL, DDBJ). The initial 
deposition of a sequence record is referred to as 
version 1. If the sequence is updated, the version 
number is incremented, but the Accession number will 
remain constant.</p>
