DNA is found.
A
Only in cytoplasm
B
Only in nucleus
C
In both cytoplasm
D
In hybrid form only
Explanation: 

Detailed explanation-1: -It is now known that small circular chromosomes, called extranuclear, or cytoplasmic, DNA, are located in two types of organelles found in the cytoplasm of the cell. These organelles are the mitochondria in animal and plant cells and the chloroplasts in plant cells.

Detailed explanation-2: -In eukaryotes, DNA is housed within the nucleus, but in prokaryotes, DNA is located directly within the cellular cytoplasm, as there is no nucleus available.

Detailed explanation-3: -Final answer: RNA could be found in both the nucleus and the cytoplasm.

Detailed explanation-4: -In eukaryotic cells, the DNA is contained inside the cell’s nucleus and there it is transcribed into RNA. The newly synthesized RNA is then transported out of the nucleus into the cytoplasm, where ribosomes translate the RNA into protein.

Detailed explanation-5: -Deoxyribonucleic Acid (DNA) is found mainly in the nucleus of the cell, while Ribonucleic Acid (RNA) is found mainly in the cytoplasm of the cell although it is usually synthesized in the nucleus.
