Circular double stranded dna
WebJun 8, 2024 · plasmid: a circle of double-stranded DNA that is separate from the chromosomes, which is found in bacteria and protozoa Characteristics of Eukaryotic … WebThe reference state (or parameter) L0 of a circular DNA duplex is its relaxed state. In this state, its writhe W = 0. Since L = T + W, in a relaxed state T = L. Thus, if we have a 400 bp relaxed circular DNA duplex, L ~ 40 (assuming ~10 bp per turn in B-DNA). Then T ~ 40 . Positively supercoiling: T = 0, W = 0, then L = 0 T = +3, W = 0, then L = +3
