"In FLT PET imaging, a radiopharmaceutical similar in chemical composition to the nucleoside deoxythymidine is used, to which a hydroxyl group is replaced with a radioactive fluorine atom: [18F] -FLT 2,3. The radiopharmaceutical, phosphorylated by thymidine kinase, is incorporated into the DNA 7; as a proliferation marker, it finds its best use in oncological diagnostics 3."
"Nucleotides, the constituent units of nucleic acids, are made up of simpler molecules called nucleosides and inorganic phosphate (H3PO4). Each nucleoside, in turn, is made up of a monosaccharide (D-ribose in RNA and 2-deoxy-D-ribose in DNA) and a heterocyclic base 4."

"Heterocyclic bases, also known as nitrogenous bases, are divided into two main classes: purines and pyrimidines. Adenine (A) and guanine (G) belong to the purines; cytosine (C) and thymine (T) (replaced by uracil (U) in RNA) conversely belong to the pyrimidines 4."
