 Locating Genetic Information

Base Pair

A base is one of the smallest meaningful units of genetic information inside a gene. There are four bases: adenine (A), guanine (G), cytosine (C), and thymine (T). They are arranged in pairs, which is why they are referred to as base pairs. When combined into DNA, each base has only one pairing partner. T always pairs with A. C always pairs with G.

If the chain between the two breaks, free nucleotides floating around inside the cell will attach themselves to the exposed bases of the separated chains. This results is two identical copies of the original DNA molecule. This is how hereditary information is passed from one generation of cells to another.
