A. It's purpose was to help us learn about the density of Earth's upper atmosphere.
Transcription doesn't have to be as accurate as replication. The answer is simple that transcripts can not be store permanently. And so it is not accurate. as far as the question of the accuracy of replication concern, it is consider more accurate because of the following steps taking place in this process:
1) high selectivity of DNA polymerase
2) exonucleatic proofreading
The purpose of the delay in the conduction of the action potential is to allow the atria to complete their contraction, before the ventricles contract.
<h3>What are the atria?</h3>
The atria are two different heart sections/chambers located at the upper region of the heart.
The atria play a fundamental role during the during heart cycle, i.e. they act as blood reservoirs in the systole.
In conclusion, the purpose of the delay in the conduction of the action potential is to allow the atria to complete their contraction.
