What is the purpose of DNA?

Answer 1

DNA is the blueprint of life. It dictates eye color, bone structure, blood type, basically everything about you. You get one half of your genome from your mother's egg cell and the other half from your father's sperm cell. This blueprint then controls how you, as an embryo develops, and further down, how you as a baby will also develop. The purpose of DNA is to not only control development, but it is also pass down information as well. Most advantages in the genome will be passed down to the next descendant, causing the general population to eventually evolve, providing life with ever-changing beings.

The main purpose of DNA is to store and retain your genetic information. DNA contains the biological information needed to construct and maintain a living organism. It contains all the information to make the enzymes needed for all the chemical reactions taking place in your body. DNA makes you who you are. It has all your heredity info, like your hair and eye color, your height, your blood type, your personality, etc. No two person's DNA is exactly the same, not even twins, and your DNA will change over time. DNA also serves as an efficient way of passing along your genetic information to your offspring.

Answer 2

It is the genetic material(like a blue print), codes for no of genes. Those genes are responsible for making proteins inside the cell or living things. And proteins do the cellular structural and functional roles to make life possible!
