Question: 1 / 400

Which part of the cell is responsible for containing the genetic material?

Nucleus

The nucleus is the part of the cell that serves as the control center, housing the genetic material, which is predominantly composed of DNA. This genetic material is essential for regulating cellular activities, including growth, metabolism, and reproduction. The nucleus contains the chromosomes that carry the genetic instructions necessary for the development and functioning of the organism.

In contrast, the cytoplasm is the gel-like substance within the cell that contains various organelles but does not possess genetic material itself. The cell membrane functions as a protective barrier, regulating what enters and exits the cell, but it does not contain genetic material. Ribosomes are responsible for protein synthesis and do not house genetic material either. Thus, the nucleus is uniquely designated for the containment of genetic material, making it the correct answer.
