Bacteria; Deinococcus-Thermus; Deinococci; Deinococcales; Deinococcaceae; Deinococcus

Species

D. radiodurans, D. radiodurans R1

NCBI: Taxonomy Genome

Description and significance

Genome structure

The genome of D. radiodurans consists of four major parts. The complete sequence of the R1 strain has 3,284,156 base pairs made up of two circular chromosomes (2,648,638 and 412,348 base pairs), a major plasmid (177,466 base pairs), and a small plasmid (45,704 base pairs). No current research shows whether or not these plasmids contribute specifically to functionality or virality. However, it is known that multiple copies of each gene are found on all the chromosomes and plasmids, which most likely contributes to its amazing repair capabilities associated with its radiation resistance.
