internal structures and external appendages. Unlike mammals and other eukaryotes, bacteria do not possess a nucleus; instead, the chromosomal DNA is found in a dense region of cytoplasm known as the nucleoid. Extra ring-shaped DNA is
1.A linear strand of DNA and associated proteins in the nucleus of eukaryotic cells that carries the genes and functions in the transmission of hereditary information. 2.A circular strand of DNA in bacteria and archaea that contains the hereditary information necessary for cell life. ...
Ring chromosomes are circular DNA molecules that occur commonly in organisms such as viruses and bacteria, but only rarely in humans, with an incidence of ~1:50,000 [78]. Ring chromosomes typically form due to two double-stranded DNA breaks. As the DNA circularizes the ring chromosome can ...
DNA ENCODING RING ZINC-FINGER PROTEIN AND THE USE OF THE DNA IN VECTORS AND BACTERIA AND IN PLANTSThe present inventions relate to compositions and methods for providing stress tolerant transgenic plants comprising a RING domain zinc-finger motif transcription factor protein. More particularly, the ...

The CRISPR system in bacteria and archaea provides adaptive immunity against mobile genetic elements. Type III CRISPR systems detect viral RNA, resulting in the activation of two regions of the Cas10 protein: an HD nuclease domain (which degrades viral DNA)1,2 and a cyclase domain (which synth...
Except for the bacterial Phylum Firmicutes, for which FlgH and FlgI are not necessary, due to the thick PG layer that holds the rod, the LP-ring is required by most Gram-negative bacteria to form functional flagella6. The L- and P-rings are anchored to the lipopolysaccharide layer of ...
During DNA repair, the ends of a double-stranded break are resected by a nuclease to leave single-stranded tails. The tails pair with homologous sequences, usually within the sister chromatid. This preference is enforced by cohesin, a ring-like complex that holds the sister chromatids in close...
