Answer:
DNA primers
Explanation:
PCR uses short DNA segments called as primers. These primers become paired with the template DNA strands and are being elongated by the DNA polymerase enzyme (Taq polymerase). On the other hand, in vivo DNA replication does not use the DNA primers. Primase is the enzyme that makes RNA primers with free 3' OH end which is then elongated by DNA polymerases. The RNA primers are synthesized when the primase enzyme makes a short RNA copy of the DNA template strand.
Answer:
They adapt to fill slightly different niches

Answer:
The answer is A.
Explanation:
The permeability of the pacemaker cell's membrane is the factor that controls the density of the materials inside the cell which also includes sodium and that controls the neurons and muscles. So if we were able to artificially alter the pacemaker cell's membrane parmeability, for the heart it would result in a quicker satisfaction of the threshold value and therefore would increase the heart rate.
