Wikipedia
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. In RNA, thymine is replaced by the nucleobase uracil. Thymine was first isolated (from calves' thymus glands) in 1893 by Albrecht Kossel and Albert Neumann.
Usage examples of "thymine".
Spiraling pairs of cytosine, guanine, adenine, and thymine: we know these are instructions for growth, for the development of life, all coded in sequences of paired elements.
They represented the nucleotides adenine, thymine, guanine, and cytosine.
The toggle must have been set for DNA mode, since the buttons were displaying the Neanderthal glyphs for adenine, guanine, thymine, and cytosine.
Glutamic acid, without which ammonia accumulates in the brain and kills, dribbled along the floor while they glared, and D-ribose, and D-2-deoxyribose, adenine, guanine, uracil, cytosine, thymine and 5-methyl cytosine without which no thing higher than a trilobite can pass on its shape and meaning to its next generation.
The toggle must have been set for DNA mode, since the buttons were displaying the Neanderthal glyphs for adenine, guanine, thymine, and cytosine.
Each side of these base pairs can either be an adenine -thymine or a guanine -cytosine bond, and they can be aligned either direction, so there are four choices.
In fact, adenine, guanine, thymine, and cytosine molecules have quite different structures, and their electron density distributions as seen by a scanning probe microscope are readily distinguished by an experienced eye.
