Thymine, also known as 5-methyluracil, is a chemical found in the nucleic acid DNA. DNA holds the genetic code for living cells.

In RNA thymine is swapped with uracil (another chemical) to represent the same genetic information. In DNA, thymine (T) connects to adenine (A) by two hydrogen bonds. These bonds hold the two strands of the DNA double helix structure together.
