Recall that nucleic acids DNA and RNA are composed of nitrogenous bases, sugars, and phosphate groups. The key difference between DNA and RNA bases lies in one of the nitrogenous bases.
List the four nitrogenous bases found in DNA: adenine (A), thymine (T), cytosine (C), and guanine (G).
List the four nitrogenous bases found in RNA: adenine (A), uracil (U), cytosine (C), and guanine (G). Note that RNA contains uracil instead of thymine.
Understand that thymine is replaced by uracil in RNA, so any set containing thymine is not correct for RNA bases.
Therefore, the correct set of nitrogenous bases in RNA is adenine, uracil, cytosine, and guanine.
