BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Most DNA is found inside the nucleus of a cell, where it forms the chromosomes.

Detailed explanation-2: -DNA is in every cell in your body. Chromosomes are found carrying your DNA in the nucleus of your cells. DNA looks like a spiral staircase (double helix).

Detailed explanation-3: -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-4: -A chromosome is a DNA molecule that contains the genetic information for an organism. The chromosomal structure is composed of the organism’s DNA and special proteins to form the dense, coiled architecture.

Detailed explanation-5: -DNA and histone proteins are packaged into structures called chromosomes.
