The chemical reactions and pathways resulting in the formation of nucleobases, nucleosides and nucleotides. The chemical reactions and pathways resulting in the formation of pyrimidine bases, 1,3-diazine, organic nitrogenous bases. The chemical reactions and pathways involving a nucleobase, a nitrogenous base that is a constituent of a nucleic acid, e.g. the purines: adenine, guanine, hypoxanthine, xanthine and the pyrimidines: cytosine, uracil, thymine. The chemical reactions and pathways resulting in the formation of 5-methylcytosine, a methylated base of DNA. The chemical reactions and pathways resulting in the formation of a nucleobase, a nitrogenous base that is a constituent of a nucleic acid. The chemical reactions and pathways resulting in the formation of thymine, 5-methyluracil, one of the two major pyrimidine bases present (as thymidine) in DNA but not found in RNA other than (as ribothymidine) in transfer RNA, where it is a minor base. The chemical reactions and pathways resulting in the formation of uracil, 2,4-dioxopyrimidine, one of the pyrimidine bases occurring in RNA, but not in DNA. The chemical reactions and pathways resulting in the formation of cytosine, 4-amino-2-hydroxypyrimidine, a pyrimidine derivative that is one of the five main bases found in nucleic acids; it occurs widely in cytidine derivatives. The chemical reactions and pathways resulting in the formation of pyrimidine bases, 1,3-diazine, organic nitrogenous bases, beginning with the synthesis of a pyrimidine ring from simpler precursors. The chemical reactions and pathways involving pyrimidine bases, 1,3-diazine, organic nitrogenous bases.
