... Chromosomes are composed mostly of DNA. A DNA molecule is made up of four different nitrogen bases – adenine (A), thymine (T), guanine (G), and cytosine (C). These bases form the rungs of the DNA “ladder.” A single gene on a chromosome may contain anywhere from several hundred to a million or more o ...
