What is DNA?

DNA stands for deoxyribonucleic acid. DNA is vital for inheritance, coding for proteins and the genetic blueprint of life. There are 4 types of DNA: the adenine (A), the thymine (T), the guanine (G), and the cytosine (C). A and T always binds together, and G and C always binds together. The sugar and the phosphate make the backbone of the DNA chain. The DNA is arranged in a double helix.

What does it do?

DNA carries information for the structure and function of living things. Also, DNA sequences must be converted into messages that can be used to produce proteins. Each DNA sequence contains instructions to make a protein that known as gene. The RNA carries the instructions for making proteins out of the DNA and leaves the nucleus through the nuclear pore to make enzymes and proteins.
