D
Thymine
Verified step by step guidance1
Understand the basic structure of nucleic acids: DNA and RNA are composed of nucleotides, each containing a sugar, a phosphate group, and a nitrogenous base.
Identify the nitrogenous bases in DNA: DNA contains four bases: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).
Identify the nitrogenous bases in RNA: RNA also contains four bases, but instead of Thymine, it has Uracil (U). The bases in RNA are Adenine (A), Uracil (U), Cytosine (C), and Guanine (G).
Compare the bases found in DNA and RNA: Notice that the only difference between the bases in DNA and RNA is that RNA contains Uracil instead of Thymine.
Conclude which base is unique to RNA: Since Uracil is present in RNA and not in DNA, it is the base found only in RNA.
