What is the control center of a cell that contains DNA and RNA?

The control center of a cell that contains DNA and RNA is the nucleus. The nucleus plays a crucial role in the cell's functioning as it houses the cell's genetic material, which includes DNA that contains the instructions for building proteins and maintaining the cell's activities. Additionally, the nucleus is involved in the synthesis of RNA, which is essential for translating genetic information into proteins.

This central role in managing and coordinating numerous cellular functions highlights why the nucleus is considered the control center of the cell. In contrast, the cytoplasm is the fluid that fills the cell and contains various organelles but does not house genetic material, while mitochondria are often referred to as the powerhouse of the cell, primarily involved in energy production. Ribosomes are responsible for protein synthesis, but they do not contain genetic material themselves.
