A pseudo form of its nucleoside is found in the T arm of a "transfer" molecule.
Homo-polymers consisting of this compound were used in the Nirenberg and Matthaei experiment. In rho-independent termination, a hairpin structure is followed by residues of this compound. Colo-rectal cancer can be treated with the 5-fluoro analog of this compound. A pseudo form of its nucleoside is found in the T arm of a "transfer" molecule. This pyrimidine is synthesized from the methylation of thymine or the deamination of cytosine. In a certain single-stranded molecule, it forms base pairs with adenine. For 10 points, name this base found in RNA but usually not DNA.
