10 Αυγ 2020 · Uracil may arise in DNA as a result of spontaneous cytosine deamination and/or misincorporation of dUMP during DNA replication. In this paper we will review: (i) sources of the origin of uracil in DNA; (ii) some properties of the enzymes responsible for the excision of uracil and their role in the I ….

3 Μαρ 2009 · 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 generated by activation-induced cytosine deaminase (AID) in B cells is a normal intermediate in adaptive immunity.
1 Δεκ 2010 · Uracil existing in DNA may arise as a result of spontaneous deamination of cytosine (leading to U:G mispairing) or from incorporation of dUMP during replication in place of dTMP leading to U:A pairing.
The lower panel lists the specific DNA repair pathways that are instigated to repair DNA damages: mismatch repair corrects replication errors and other base mismatches; base excision repair removes base adducts, uracil, abasic sites and oxidative lesions; single strand break repair pathways repairs single stranded breaks in the DNA backbone ...
