BIOMOLECULES AND ENZYMES

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: -In organisms called eukaryotes, DNA is found inside a special area of the cell called the nucleus. Because the cell is very small, and because organisms have many DNA molecules per cell, each DNA molecule must be tightly packaged.

Detailed explanation-3: -DNA is found mostly in the cell nucleus, but another type of nucleic acid, RNA, is common in the cytoplasm.

Detailed explanation-4: -DNA is present in nucleus and some cell organelles like chloroplast and mitochondria.
