According to Chargaff's Rule, which base pairs with Adenine?

Explanation:
Chargaff's rule describes how bases pair in the DNA double helix: adenine pairs with thymine, and cytosine pairs with guanine. This pairing happens because adenine has two hydrogen-bonding sites that align perfectly with thymine, giving two stable hydrogen bonds and a complementary shape. So the base that pairs with adenine is thymine. Cytosine pairs with guanine (three hydrogen bonds), and adenine does not pair with itself in normal DNA. The equal amounts of A and T (and of G and C) in double-stranded DNA come from this specific pairing.
