Uracil in DNA results from deamination of cytosine, resulting in mutagenic U : G mispairs, and misincorporation of dUMP, which gives a less harmful U : A pair. At least four different human DNA ...

The chemical structure of uracil, showing its single-ring pyrimidine structure. Uracil forms hydrogen bonds with adenine in RNA, contributing to the molecule's structure and function. (Image: Public ...

Analysis of samples retrieved from the asteroid Ryugu by the Hayabusa2 mission revealed the presence of uracil, a fundamental nucleobase for RNA and DNA. The pristine nature of the Ryugu samples ...

Uracil in DNA may result from incorporation of dUMP during replication and from spontaneous or enzymatic deamination of cytosine, resulting in U:A pairs or U:G mismatches, respectively. Uracil ...

Samples from the asteroid Ryugu collected by the Hayabusa2 mission contain nitrogenous organic compounds, including the nucleobase uracil, which is a part of RNA. Samples from the asteroid Ryugu ...

SINCE the introduction of nitrogen mustard, methyl-bis-β-(chloroethyl)-amine, or HN 2 (Fig. 1), as a therapeutic agent in human cancer a number of analogues and related alkylating agents have been ...
