GENERAL HISTOLOGY

Detailed explanation-1: -Explanation : The Nucleus is a large organelle that stores the cell’s DNA (deoxyribonucleic acid). The nucleus controls all of the cell’s activities, such as growth and metabolism, using the DNA’s genetic information.

Detailed explanation-2: -Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA). Mitochondria are structures within cells that convert the energy from food into a form that cells can use.

Detailed explanation-3: -Control room of the cell is the nucleus. It guides the cells to carry out various metabolic processes.

Detailed explanation-4: -Other than the nucleus, the mitochondria are the organelles that contain DNA. In contrast to chromosomal DNA, the mitochondria contain nucleic material known as mitochondrial DNA.
