What are proteins?</h3>
Proteins are big, complex molecules that play a number of important tasks in the human body. They are essential for the structure, function, and control of the body's tissues and organs, and they do the majority of their job in cells.
DNA (deoxyribonucleic acid) is the molecule that conveys genetic information for an organism's development and function. DNA is made up of two connected strands that loop around each other like a twisted ladder, giving it the shape of a double helix. The backbone of each strand is made up of sugar (deoxyribose) and phosphate groups that alternate. Each sugar has one of four bases attached to it: adenine (A), cytosine (C), guanine (G), or thymine (T).
