These relationships are often called the rules of Watson-Crick base pairing, named after the two scientists who discovered their structural basis.

Its principal role is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins, although in some viruses RNA rather than DNA carries the genetic information.
The rules of base pairing (or nucleotide pairing) are:
A with T: the purine adenine (A) always pairs with the pyrimidine thymine (T)
C with G: the pyrimidine cytosine (C) always pairs with the purine guanine (G)
The purine adnenine (A) will pair with the pyrimidine uracil (U) instead of thymine (T)
Base pairing is achieved by hydrogen bonds, a type of noncovalent reaction.
Why not A with C and G with T?
In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes.

These common features are:
DNA, the genetic material contained in one or more chromosomes and located in a nonmembrane bound nucleoid region in prokaryotes and a membrane-bound nucleus in eukaryotes
Plasma membrane, a phospholipid bilayer with proteins that separates the cell from the surrounding environment and functions as a selective barrier for the import and export of materials
Cytoplasm, the rest of the material of the cell within the plasma membrane, excluding the nucleoid region or nucleus, that consists of a fluid portion called the cytosol and the organelles and other particulates suspended in it
Ribosomes, the organelles on which protein synthesis takes place
