D
Ribose
Verified step by step guidance1
Recall the four nitrogenous bases found in DNA: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).
Recall the four nitrogenous bases found in RNA: Adenine (A), Uracil (U), Cytosine (C), and Guanine (G).
Compare the bases in DNA and RNA to identify which bases are common to both molecules.
Note that Thymine is found only in DNA, while Uracil is found only in RNA.
Conclude that Adenine is a nitrogenous base present in both DNA and RNA.
