NEET BIOLOGY

Detailed explanation-1: -The nucleus is one of the most obvious parts of the cell when you look at a picture of the cell. It’s in the middle of the cell, and the nucleus contains all of the cell’s chromosomes, which encode the genetic material.

Detailed explanation-2: -Inside the nucleus, chromatin (DNA wrapped around proteins, described further below) is stored in a gel-like substance called nucleoplasm. Enclosing the nucleoplasm is the nuclear envelope, which is made up of two layers of membrane: an outer membrane and an inner membrane.

Detailed explanation-3: -The nucleus is a membrane-enclosed organelle, found in most eukaryotic cells, which stores the genetic material (DNA).

Detailed explanation-4: -By housing the cell’s genome, the nucleus serves both as the repository of genetic information and as the cell’s control center. DNA replication, transcription, and RNA processing all take place within the nucleus, with only the final stage of gene expression (translation) localized to the cytoplasm.
