Which nitrogenous base is found in both DNA and RNA?
A
Deoxyribose
B
Adenine
C
Uracil
D
Ribose
Verified step by step guidance1
Understand that nitrogenous bases are the molecules that make up the rungs of the DNA and RNA structures, pairing specifically to encode genetic information.
Recall the four main nitrogenous bases in DNA: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).
Recall the four main nitrogenous bases in RNA: Adenine (A), Uracil (U), Cytosine (C), and Guanine (G).
Compare the bases in DNA and RNA to identify which base is common to both molecules.
Note that Deoxyribose and Ribose are sugars, not nitrogenous bases, so they are not the correct answer.
