Answer:
The protein phosphatase-1 dephosphorylates the residues of serine, which are phosphorylated by the protein kinase A. The cyclic-AMP inducible genes are stimulated by CREB that is phosphorylated by protein kinase A. Thus, overexpression of protein phosphatase 1 would prevent their induction.
Although, protein phosphatase 1 would not influence the function of cAMP-gated ligand channels, as these channels are opened directly by binding of cAMP rather than by protein phosphorylation.
Heredity or something like that I don’t speak English sorry
The answer is C. large changes in allele frequencies can occur in a short time.
Genetic drift is a change in the frequency of alleles in a population as a result of random sampling of organisms and it decreases genetic variation of the population. In specific circumstances, large and rapid changes in allele frequencies can occur in a short time. The smaller the population, the more susceptible it is to genetic drift.
