"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 " - Circular double stranded dna

Webdouble-stranded circular; double-stranded linear Describe the organization of the eukaryotic chromosome. The DNA is wound around proteins called histones. The histones then stack together in a compact form that creates a fiber that is 30-nm thick. The fiber is further coiled for greater compactness. WebDNA supercoiling is important for DNA packaging within all cells. Because the length of DNA can be thousands of times that of a cell, packaging this genetic material into the cell …
