... The DNA molecule is like a ladder twisted into a spiral The sides of the ladder are the same in all DNA molecules, but the rungs are what make the variations. Each rung pairs up two of the following chemicals: guanine (G), cystosine (C), adenine (A) and thiamine (T). The arrangement of these four ch ...
