Explanation:
Detailed explanation-1: -The nucleus (Figure 6) serves as the cell’s command center, sending directions to the cell to grow, mature, divide, or die. It also houses DNA (deoxyribonucleic acid), the cell’ s hereditary material.
Detailed explanation-2: -The instructions stored within DNA are read and processed by a cell in two steps: transcription and translation. Each of these steps is a separate biochemical process involving multiple molecules. During transcription, a portion of the cell’s DNA serves as a template for creation of an RNA molecule.
