Where is DNA found in an animal cell?
A
inside a gene
B
in the cytoplasm
C
in a strand of DNA
D
inside of the nucleus
Explanation: 

Detailed explanation-1: -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-2: -DNA is found in the nucleus. Yes, all animal cells have DNA.

Detailed explanation-3: -In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.

Detailed explanation-4: -The nucleus contains nearly all of the cell’s DNA, surrounded by a network of fibrous intermediate filaments and enveloped in a double membrane called the nuclear envelope. The nuclear envelope separates the fluid inside the nucleus, called the nucleoplasm, from the rest of the cell.
