What is DNA and why is it important?

DNA is a complex, long-chained molecule that encodes the genetic characteristics of a living organism. In most plants and animals, DNA is packaged with ribonucleic acid and proteins into compact structures called chromosomes that reside in the cell nucleus.

Similarly, you may ask, what is the main purpose of DNA?

Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions for the development and function of living things. All known cellular life and some viruses contain DNA. The main role of DNA in the cell is the long-term storage of information.

Why do we need a DNA?

DNA is a very long molecule made up of repeating units called nucleotides. The backbone of the nucleotides is the same, but the "bases" attached to the backbone can change. Without DNA, we would not have a way for our bodies to know how to grow and develop, or a way to reproduce.
