Webb6 maj 2024 · The enzyme for synthesis of thymine (dTTP) is thymidylate synthase, which requires dUMP as substrate. Thus, it is not possible to create rTTP instead of dTTP. Conversion of uracil to thymine requires energy, meaning uracil is energetically less expensive than thymine. Webb22 juni 2024 · Four nitrogenous bases—cytosine, thymine, adenine, and guanine—can be found on strands of DNA. In terms of their chemical structure, cytosine and thymine are pyrimidines and adenine and guanine are purines. Adenine and thymine (A and T) always pair together, and guanine and cytosine (G and C) always pair together.
