INFOGRAPHIC 7.2 DNA IS MADE OF TWO STRANDS OF NUCLEOTIDES
DNA is a double-stranded molecule. Each of the two strands consists of a chain of subunits called nucleotides that are bonded together. There are four types of nucleotide: adenine (A), thymine (T), guanine (G), and cytosine (C). Nucleotides are the building blocks of DNA.
