Which organelle is the storehouse for most of a cell’s genetic information?
A
mitochondrion
B
centriole
C
chloroplast
D
nucleus
Explanation: 

Detailed explanation-1: -The nucleus is the largest organelle in the cell and contains most of the cell’s genetic information (mitochondria also contain DNA, called mitochondrial DNA, but it makes up just a small percentage of the cell’s overall DNA content).

Detailed explanation-2: -The storehouse of information in a cell is the gene. A gene is a piece of DNA that can code for a protein or RNA. They are responsible for passing information from one generation to another.

Detailed explanation-3: -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-4: -The nucleus is a membrane-bound organelle that is found in the eukaryotic cells. It is the most important and essential part of the cell. The nucleus is the storehouse of genetic information, that is the DNA.

Detailed explanation-5: -Nucleus. Known as the cell’s “command center, ” 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.
