The nature of archaeal and bacterial genomes
http://evolution-textbook.org/content/free/notes/ch06_Notes.html WebGenomes of Archaea. Archaeal genomes resemble bacterial genomes with respect to form, size, and complexity. All known archaeal genomes are circular DNAs and range in size from 0.5 to 5.8 Mbp. The archaeal genome smaller than 1 Mbp is found in a symbiont that derives nutrients from a host, and the small size of this genome reflects the loss of ...
