WebThe genetic material of cyanobacteria is made up of naked DNA fibrils found dispersed in the central region of the cytoplasm. Like other prokaryotes, they lack membrane-bound organized nucleus. The exact number of genomes per cell is not yet known; it has recently been reported that Agmenellum contains 2, 3 or more copies of its genetic material. WebNotably, the SI3-head module forms a SI3-σ arch that seals the main cleft of RNAP and stabilizes the transcription initiation complex. Biochemical and genetic evidence suggests the importance of this SI3-σ arch interaction in RNAP-promoter open complex (RPo) formation.
