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 WebImage transcription text. 22) In E. coli, the genetic material is composed of A) circular, double-stranded DNA B) linear, double-stranded DNA C) RNA and protein D) circular, double-stranded RNA E) polypeptide chains 23) Type I topoisomerases differ from type II topoisomerases in that the type I enzymes A) cleave one strand of a double helix B ...

WebThis is then translocated to the nucleus, where the partially double stranded DNA is 'repaired' by the viral polymerase to form a complete circular dsDNA genome (called covalently-closed-circular DNA or cccDNA). The genome then undergoes transcription by the host cell RNA polymerase and the pregenomicRNA (pgRNA) is sent out of the nucleus.
