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 ...

Deamination of cytosine to uracil in a G-C base pair is a major promutagenic event, generating G-C→A-T mutations if not repaired before DNA replication. Archaeal family B DNA polymerases are uniquely ...

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 ...
