Why are prophase and metaphase important in contributing to the maintenance of complex organisms like you and me?

The importance of prophase and metaphase is discussed below.

Explanation:

Prophase is the first step in mitosis. In the prophase, the chromatids change into chromosomes. The chromosomes become visible when the chromatids condense. This phase ensures that the right number of chromosomes is incorporated into each daughter cell.

In the metaphase, the chromosomes are aligned in the center. The stage of metaphase acts as a checkpoint to ensures that the chromosomes have been aligned properly, before moving them to the next phase.

b, acidosis

dna is made up of six smaller molecules -- a five carbon sugar called deoxyribose, a phosphate molecule and four different nitrogenous bases (adenine, thymine, cytosine and guanine).
