DNA is a structure made up of two coiled polynucleotide chains with nitrogenous bases present in chromosomes. These chromosomes are present in the nucleus of the cell. These cells together form an organism.

What are Cells?

Cell is define as the smallest unit which can live on its own and that makes up all living organisms and the tissues of the body. A cell has three main parts:

1. The cell membrane

2.The nucleus

3. The cytoplasm.

A nucleus is defined as the membrane-enclosed organelle within a cell that contains chromosomes. It is an array of pores, or pores, in the nuclear membrane that allow the selective passage of certain molecules, such as proteins and nucleic acids, into and out of the nucleus.

Chromosomes are define as the threadlike structures made of protein and a single molecule of DNA which serve to carry the genomic information from cell to cell. These DNA (Deoxyribonucleic acid) is a polymer which is composed of two polynucleotide chains that coil around each other to form a double helix consisting of nitrogenous bases.

Thus, DNA is a structure made up of two coiled polynucleotide chains with nitrogenous bases present in chromosomes. These chromosomes are present in the nucleus of the cell. These cells together form an organism.
