The National Center for Biotechnology Information taxonomy page for Gemmata obscuriglobus: [1]

Gemmata obscuriglobus is a spherical budding bacteria isolated from a freshwater damn in Queensland, Australia. This bacteria is interesting because it exhibits several structures and cellular processes that are typically reserved for only eukaryotic cells.

Genome Structure

The genome of Gemmata obscuriglobus is made up of DNA contained in the fibrillar, membrane-bounded nucleoid which is then surrounded by a another membrane as stated before. The genome consists of 9.16 million base pairs, consisting of 8,080 genes producing 7,989 proteins discovered thus far. The DNA does not contain chromosomes, but a circular piece of DNA that is characteristic to most all prokaryotes.

Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence?
