Which part of a cell contains genetic information?

The nucleus is the part of a cell that houses the genetic information. Within the nucleus, DNA is organized into structures called chromosomes, which carry the genes that dictate various functions and traits of the organism. This genetic information is crucial for cell growth, development, reproduction, and the overall functioning of the organism.

The other components mentioned do not contain this genetic material. The cytoplasm is the fluid that fills the cell and contains various organelles, but it does not house genetic information. The cell membrane serves as a barrier regulating what enters and exits the cell, while ribosomes are responsible for protein synthesis based on the information encoded in the DNA, but they do not store or contain genetic information themselves.
