What is nucleus
1 answer
The nucleus is a membrane-bound organelle found in eukaryotic cells. It is often referred to as the "control center" of the cell as it contains the genetic material (DNA) and is responsible for regulating gene expression and cell function. The nucleus is surrounded by a double membrane called the nuclear envelope, which contains pores that control the movement of molecules in and out of the nucleus. Within the nucleus, the DNA is organized into structures called chromosomes, which carry the genetic information necessary for cell growth, development, and reproduction. The nucleus also contains the nucleolus, a region responsible for the production and assembly of ribosomes, which are essential for protein synthesis.
