There are five different nucleotides that are the building blocks of DNA and RNA.

The table below gives:

• the names of the nucleotides
• the nucleic acid (DNA or RNA) it is found in
• the single letter code for the nucleotide

Nucleotide		Nucleic Acid		1 Letter Code
Adenine		DNA, RNA		A
Cytosine		DNA, RNA		C
Guanine		DNA, RNA		G
Thymine		DNA		T
