Which set correctly lists the four nitrogenous bases found in DNA?
A
Adenine, thymine, cytosine, guanine
B
Adenine, thymine, cytosine, uracil
C
Adenine, thymine, guanine, uracil
D
Adenine, uracil, cytosine, guanine
Verified step by step guidance1
Recall that DNA is composed of four nitrogenous bases, which are divided into two categories: purines and pyrimidines.
Identify the purines in DNA: adenine (A) and guanine (G).
Identify the pyrimidines in DNA: cytosine (C) and thymine (T).
Remember that uracil (U) is found in RNA, not DNA, so it should not be included in the list of DNA bases.
Combine the correct bases to list the four nitrogenous bases found in DNA: adenine, thymine, cytosine, and guanine.
