Which nitrogenous bases are found in a strand of DNA?
A
Adenine, Thymine, Guanine, Uracil
B
Adenine, Thymine, Cytosine, Guanine
C
Adenine, Uracil, Cytosine, Guanine
D
Adenine, Thymine, Cytosine, Uracil
Verified step by step guidance1
Understand that DNA is composed of four nitrogenous bases that pair up to form the rungs of the DNA double helix.
Recall that the four nitrogenous bases found in DNA are Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).
Recognize that Uracil (U) is not found in DNA; it is a base found in RNA, replacing Thymine.
Identify the correct pairing of bases in DNA: Adenine pairs with Thymine, and Cytosine pairs with Guanine.
Review the options provided and select the one that includes Adenine, Thymine, Cytosine, and Guanine as the bases found in DNA.
