de·ox·y·ur·i·dine

(dē-oks'ē-yūr'i-dēn),
A derivative of uridine in which one or more of the hydroxyl groups on the ribose moiety has been replaced by a hydrogen; for example, 2'-deoxyuridine is a rare naturally occurring deoxynucleoside.

Folate is an essential nutrient acting as methyl donor for conversion of deoxyuridine monophosphate (dUMP)to deoxythymidine monophosphate required for DNA synthesis and repair.
Mutations are heritable changes in the DNA, can be either naturally occurring or man-made, and form the basis of much genetic variation [26], there are three main types of mutation: Substitution, Insertion and Deletion, mutagen is distinguished into chemical mutagen such as 5-bromo- deoxyuridine, colchicine and 2, 4 Dinitroaniline [28] and, physical mutagen such as UV, X-radiation and Gamma rays [27,28] and biological mutagen such as Helicobacter pylori bacterium [41].
In folate pathway mechanism deoxythymidine monophosphate (dTMP) (dTMP) is produced from deoxyuridine monophosphate (dUMP) by oxidation of tetrahydrofolate to dihydrofolate catalysed by dihydrofolate reductase (DHFR) (Hyde 2005; Abali et al.
