Circular double stranded dna
WebThe linking number (Lk) of a closed-circular, double-stranded DNA molecule is changed by: breaking a strand, unwinding or rewinding the DNA, then rejoining it. For a closed-circular DNA molecule of 10,000 base pairs in the fully relaxed form, the linking number (Lk) is about: 950. WebApr 9, 2024 · Prokaryotic DNA: Prokaryotic DNA is double-stranded circular DNA that remains diffused in a dense region of cytoplasm called the nucleoid. There is no nuclear membrane surrounding the DNA in prokaryotes. The single circular DNA represents a single chromosome.

They replicate autonomously and may encode proteins which, although not normally essential to bacterial survival, may confer resistance to antibiotics.
