Transcript text: In DNA replication, $\qquad$ pairs with thymine, and cytosine pairs with $\qquad$
Multiple Choice
purine, alanine
adenine; guanine
cytosine; thymine
None of the answer choices are correct.
guanine; adenine
Solution
The answer is adenine; guanine.
Explanation for each option:
purine, alanine: This is incorrect. Purines are a category of nitrogenous bases that include adenine and guanine, but alanine is an amino acid, not a nitrogenous base.
ices: This is not relevant to DNA replication and is incorrect.
adenine; guanine: This is correct. In DNA replication, adenine pairs with thymine, and cytosine pairs with guanine.
cytosine; thymine: This is incorrect. Cytosine pairs with guanine, not thymine.
None of the answer choices are correct: This is incorrect because the correct answer is provided in the options.
guanine; adenine: This is incorrect. Guanine pairs with cytosine, not adenine.
Summary:
The correct answer is adenine; guanine. In DNA replication, adenine pairs with thymine, and cytosine pairs with guanine.
