Thymine

Thymine

Thymine is one of the four nitrogenous bases found in DNA and RNA along with Adenine, Cytosine, Guanine and Uracil. It is a Pyrmidine base, meaning it consists of one six-member ring. Thymine is only found in DNA. In RNA, Uracil takes the place of Thymine. Thymine always pairs up with Adenine forming two Hydrogen bonds. [LM] {GE} {RH}
