WebIn eukaryotes with large DNA molecule, there may be many initiation points (origin) of replication which finally merge with one another. 3. Unwinding of DNA molecule: The DNA double helix unwinds and uncoils into single strands of DNA by breakdown of weak hydrogen bonds. Unwinding of helix is helped by enzyme helicases. WebMay 3, 2004 · The processivity of DNA unwinding is defined as the probability of the helicase unwinding a base pair versus helicase dissociating from that position on the DNA. The measured processivity shows that the helicase unwinds, on an average, 60 bp (at 2 mM dTTP) before it dissociates from the DNA [1/(1 - P )] and 33 bp at 200 μM dTTP. file tax return meaning https://dalpinesolutions.com
