Which of the following bases pairs with adenine in DNA?

In DNA, adenine pairs specifically with thymine through the formation of hydrogen bonds, creating a stable base pair that is crucial for the structure of the double helix. The complementarity of bases is fundamental to the way DNA is organized and replicated, as it ensures that the sequences can be accurately copied during cell division.

Cytosine and guanine form a different pair in DNA, while uracil is found in RNA and replaces thymine in RNA structures. Thus, the pairing rule for adenine is exclusive to thymine in DNA, making it essential for understanding genetic coding and the mechanisms of heredity.
