Which base is Thymine?

Explanation:
Thymine is one of the bases used to store genetic information in DNA. DNA has four bases: adenine, thymine, cytosine, and guanine. In contrast, RNA uses adenine, uracil, cytosine, and guanine; thymine is not present in RNA, with uracil taking its place. Thymine pairs with adenine in DNA through two hydrogen bonds, helping to stabilize the DNA double helix. Since thymine exists in DNA but not in RNA, the best answer is that thymine is a DNA base.
