NEET BIOLOGY

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 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-3: -The majority of D.N.A is kept in the nucleus, a small compartment within the cell. A small portion of it is also found in another compartment known as the mitochondrion. The location of DNA depends on the type of organism.

Detailed explanation-4: -The nucleolus contains DNA, RNA and proteins. It is a ribosome factory.

Detailed explanation-5: -DNA can be found in each cell in your body. The majority of your DNA resides in the nucleus (center) of each cell in your body and some DNA lives in mitochondria (little organelles inside of your cells that produce energy).
