The answer would be: <span>A. Mitochondrial DNA is beneficial in both of these cases
</span>
Mitochondrial DNA or mtDNA is DNA that found in the mitochondrial. Mitochondrial DNA only inherited from mother, so it's relatively unchanged than nuclear DNA that mixed from father and mother.
Mitochondrial DNA has higher mutation rate in animals because it doesn't have repair mechanism like nuclear DNA. These mutations can be used as a clue for how close the relation of an organism to others.
This makes analyzing the ancestral relationship of organisms that closely or distantly related easier.
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.
The inheritance of a dominant gene E results in the free out unattached earlobe. If the lobe is attached directly to the head, the individual is homozygous recessive, and the rest genotype is present. Hope this helps.
The right answer is higher-than-average sea levels.
With the rise in CO2 level that caused an increase in air temperature and sea surface temperatures. At this time, they were the highest ever recorded. In addition, the rise in mean sea level continued and the extent of Arctic sea ice was well below normal for most of the year.
I think its the atmosphere ?????
