WebbDuring initial transcription, RNAP uses a "scrunching" mechanism, in which RNAP remains stationary on promoter DNA and unwinds and pulls downstream DNA into itself and past its active center in each nucleotide-addition cycle, resulting in generation of a stressed intermediate. After RNAP synthesizes an RNA product ~10-15 nucleotides in length ... WebbWe asked next whether the mechanism that generated the overrepresented molecules was constitutive or cell cycle-regulated and whether it occurred simultaneously to the time of activation of ORIs during DNA replication. To address this point ... (2006) Initial transcription by RNA polymerase proceeds through a DNA-scrunching mechanism. Webb3 aug. 2024 · In initial transcription, RNAP uses a “scrunching” mechanism, in which, in each nucleotide-addition cycle, RNAP remains anchored to promoter DNA, unwinds one base pair of DNA downstream of the RNAP active center, pulls the unwound single-stranded DNA (ssDNA) into and past the RNAP active center, and accommodates the … howick self catering accommodation
