GENERAL HISTOLOGY

Detailed explanation-1: -Nucleus is large, spherical organelle present in all cells. In animal cell, it is located at the center of the cell, while in plant cell it is located at the periphery of the cell. Genetic material of plant and animal cell is found in nucleus.

Detailed explanation-2: -The nucleus (plural, nuclei) houses the cell’s genetic material, or DNA, and is also the site of synthesis for ribosomes, the cellular machines that assemble proteins. Inside the nucleus, chromatin (DNA wrapped around proteins, described further below) is stored in a gel-like substance called nucleoplasm.

Detailed explanation-3: -A nucleus, as related to genomics, is the membrane-enclosed organelle within a cell that contains the chromosomes. An array of holes, or pores, in the nuclear membrane allows for the selective passage of certain molecules (such as proteins and nucleic acids) into and out of the nucleus.
