Function of mitochondriaone function of chromatin

The most prominent roles of mitochondria are to produce the energy currency of the cell, ATP (i.e., phosphorylation of ADP), through respiration, and to regulate cellular metabolism

chromatins primary function is packaging long DNA molecules into more compact, denser structures.

Explanation:

The main function of the mitochondria is to provide energy for cellular activity by the process of aerobic respiration. In this process, glucose is broken down in the cell's cytoplasm to form pyruvic acid, which is transported into the mitochondrion.

the three components of a nucleotide are the nitrogenous base, the phosphate group and the five-carbon sugar.

sorry to break it to ya but no one can answer your question it's just

jk but i am serious about the part that most people cant answer it beacuse you did not mention the section you are talking about. but it would if you added some detail and were a bit more specific.
