Answer:
Option (D).
Explanation:
Processivity of DNA polymerase may be defined as the number of nucleotides added in the single binding event. The synthesis phase of cell cycle is fully dependent on the processivity of DNA polymerase.
The processivity of DNA polymerase depends on the sliding clamp, domains of the DNA and the interaction of DNA with enzyme. Loss of hydrogen ion at 3'OH primer does not affect processivity but important for the nucleophile attack and also effect the catalytic property of enzyme.
Thus, the correct answer is option (D).
Answer:
It could be prevent Ga from binding to the epinephrine receptor.
Explanation:
Hindering GTPase action will make G-protein to tie to adenyl cyclase for all time so Glucose is delivered persistently.
Diminishing the proclivity for GDP will build the opportunity of authoritative of GTP to G protein which thus will initiate the pathway.
On the off chance that G protein ties with adenyl cyclase it will invigorate it.
Yet, in the event that the G-protein is kept from official with epinephrine receptor, at that point the receptor can't enact trade the guanine nucleotide to G-protein for initiation. Thus the G-protein stays in latent state.
