1 DNA contains four basic building blocks or â bases â: adenine (A), cytosine (C), guanine (G) and thymine (T). 2  The order, or sequence, of these bases form the instructions in the genome. 3  DNA is a two-stranded molecule. The bases always pair together in the same way, A with T, C with G. 2  Each base pair is joined together by hydrogen bonds. 3  Each strand of DNA has a beginning and an end, called 5â (five prime) and 3â (three prime) respectively.
