Verified step by step guidance1
Identify the context of the problem: The question is asking about the nitrogenous bases found in DNA.
Recall the four nitrogenous bases that are present in DNA. These are adenine (A), thymine (T), cytosine (C), and guanine (G).
Understand the difference between DNA and RNA: DNA contains thymine, whereas RNA contains uracil instead of thymine.
Review the options provided in the problem: Check each option to see which bases are listed and compare them to the known bases in DNA.
Select the correct option: Based on the knowledge that DNA contains adenine, thymine, cytosine, and guanine, choose the option that lists these bases.
