In the double helix structure of DNA, thymine forms a base pair with adenine through two hydrogen bonds. This specific pairing is known as complementary base pairing and is essential for the stability ...

Both uracil and thymine pair with adenine, but they differ in their chemical structure. Thymine has an additional methyl group (-CH3) attached to its pyrimidine ring, while uracil lacks this group.

thymine or cytosine. These bases are the individual letters that make up DNA's code. DNA has a ladder-like structure, and normally, bases on one side of the ladder pair with a partner on the other ...
