The nucleic acids that comprise DNA are guanine, adenine, cytosine, and thymine. The nucleic acids that comprise RNA (which is produced as a copy of DNA and a template for making proteins, and also makes up the ribosomes, among other things) are the same, except instead of thymine you have uracil. There are many other nucleic acids that play different roles in the cell, but those are the main ones.
