What is the cell organelle that directs the activity of a cell that contains chromosomes with DNA?
A
nucleolus
B
nucleus
C
ribosomes
D
golgi body
Explanation: 

Detailed explanation-1: -The nucleus is the most conspicuous organelle found in a eukaryotic cell. It houses the cell’s chromosomes and is the place where almost all DNA replication and RNA synthesis occurs.

Detailed explanation-2: -The semifluid matrix found inside the nucleus is called nucleoplasm. Within the nucleoplasm, most of the nuclear material consists of chromatin, the less condensed form of the cell’s DNA that organizes to form chromosomes during mitosis or cell division.

Detailed explanation-3: -Nucleus. The nucleus serves as the cell’s command center, sending directions to the cell to grow, mature, divide, or die. It also houses DNA (deoxyribonucleic acid), the cell’s hereditary material.

Detailed explanation-4: -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.
