The correct Answer is:
To answer the question "In DNA, adenine pairs with," we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Nitrogen Bases in DNA**: - DNA consists of four nitrogenous bases: adenine (A), guanine (G), cytosine (C), and thymine (T). 2. **Understand Base Pairing Rules**: - According to Chargaff's rules (also known as the complementary base pairing rules), specific bases pair with each other: - Adenine (A) pairs with Thymine (T) - Guanine (G) pairs with Cytosine (C) 3. **Eliminate Incorrect Options**: - The question mentions adenine, so we can eliminate uracil (U) since it is not present in DNA; uracil is found in RNA. 4. **Conclude the Pairing**: - Since adenine pairs with thymine in DNA, the correct answer to the question is thymine (T). ### Final Answer: In DNA, adenine pairs with thymine. ---
