<Amber L. Hartman> is the first author of a 2010 collaborative <genomics> study reporting the complete <genome> of <Haloferax volcanii> DS2. This salt-adapted member of the <Archaea> is a useful <model organism>: it can be grown on simple defined media and investigated with <genetics> tools. A reference <genome> makes such experiments interpretable by identifying the <genes> and surrounding <DNA> being manipulated.<The Complete Genome Sequence of Haloferax volcanii DS2, a Model Archaeon by Amber L. Hartman and others>[Byline, Abstract and Introduction; PLOS ONE 5, e9605, 2010]{ref}
The study describes a main <chromosome> of about 2.85 million bases, three smaller <chromosomes> and one small <plasmid>. Thus a complete <genome> need not be a single circular <DNA> molecule. The authors explain that their chromosome terminology reflects replication properties and earlier nomenclature, while acknowledging debate over the labels. This is useful experimental context: a <gene> placed on a smaller replicating element still belongs to the organism's total genetic complement.<The Complete Genome Sequence of Haloferax volcanii DS2, a Model Archaeon by Amber L. Hartman and others>[Results and Discussion, I: Genome features; main chromosome 2.848 Mb, pHV1/pHV3/pHV4 and pHV2]{ref}
