He is the division of the autonomic nervous system associated with rest, repair, and energy storage. a. parasympathetic nervous system b. sympathetic nervous system c. somatic nervous system d. endocrine system

Option A) parasympathetic nervous system

Explanation:

The autonomic nervous system consists of two parts namely

- the sympathetic nervous system SNS, and

- the parasympathetic nervous system PNS

The PNS stimulates the same organs as SNS, but its action is opposite to SNS.

And it acts to return the body to a normal state, thus it is associated with actions such as:

- slowing heart beat

- dilates arteries,

- lowering blood pressure

- stimulating saliva secretion etc

All these actions of the PNS bring about rest, repair, and energy storage.

The mRNA transcript that is produced in the nucleus is in immature form, it had to get matured, and then its capping and tailing is done. 5' cap is added and a poly A tail is added at 3' end of this mRNA. This helps it to get matured. moreover for its maturation the non-coding regions (introns) are removed and exons are packed up again to form a mature mRNA.

This mature mRNA then proceeds to its way to the ribosomes for translation of proteins.
