thymine

one of four types of nitrogenous bases found in DNA, having the single-ring structure of a class known as PYRIMIDINES. Thymine forms part of a DNA unit called a NUCLEOTIDE and always forms complementary pairs with a DNA purine base called ADENINE. See Fig. 297 . Thymine is replaced by URACIL in RNA molecules.

In general, conductivity values of all samples have no significant increment with and without adenine or thymine. For the range of pH of distilled water samples, adenine and thymine are neutral and dissolved silicon exists as [H.sub.4]Si[O.sub.4].
As UDG cannot remove the thymine because of the deamination of a 5-mC, and the T790M mutation arises at a CpG site, we therefore examined whether deamination of 5-mC to thymine is associated with artifactual T790M mutations.
Furthermore, the bisVBT monomer similarly has photo-cross-linking capabilities due to the thymine base in its structure.
The nitrogenous bases Purines [adenine (A) and guanine (G)] and Pyrimidines [Cytosine (C), Uracil (U)and Thymine (T)] are essential building blocks of RNA and DNA.

Thymine DNA glycosylase is essential for active DNA demethylation by linked deamination-base excision repair.
(7) Sequencing results for 2 siblings with hypodontia confirmed a thymine to adenine mutation at MSX1 nucleotide 620, resulting in a Met61Lys substitution.

Organisms down to the lowliest form use nucleotides adenine, thymine, cytosine and guanine as DNA's four-letter alphabet.
"A" stands for adenine, paired with "T" for thymine; and "C" represents cysteine, paired with "G" for guanine.
The stereoisomeric aminols 11a,b were also converted into the uracil and thymine nucleosides.
