Thymine vs. Thymidine

Thyminenoun

A heterocyclic base, 5-methylpyrimidine-2,4(1H,3H)-dione; it pairs with adenine in DNA.

Thyminenoun

a base found in DNA (but not in RNA) and derived from pyrimidine; pairs with adenine

Thymine

Thymine (T, Thy) is one of the four nucleobases in the nucleic acid of DNA that are represented by the letters G–C–A–T. The others are adenine, guanine, and cytosine. Thymine is also known as 5-methyluracil, a pyrimidine nucleobase.

Thymidinenoun

The nucleoside consisting of a combination of deoxyribose and thymine

Thymidinenoun

a nucleoside component of DNA; composed of thymine and deoxyribose

Thymidine

Thymidine (other names deoxythymidine, deoxyribosylthymine, thymine deoxyriboside) is a pyrimidine deoxynucleoside. Deoxythymidine is the DNA nucleoside T, which pairs with deoxyadenosine (A) in double-stranded DNA. In cell biology it is used to synchronize the cells in G1/early S phase.
