This conversion of a DNA base from cytosine (C) to thymine (T) can result in a transition mutation. In vitro. 5-Methylcytosine can be deaminated to form thymine with use of reagents ...
A hotspot can be at an unusual base, e.g., 5-methylcytosine. Mutation rates also vary across species. Evolutionary biologists have theorized that higher mutation rates are beneficial ...
BACKGROUND: The pattern of point mutation is important for studying mutational mechanisms, genome evolution, and diseases.
In order to define the contribution of 5-methylcytosine to sunlight-induced mutations, the lacI and cII transgenes in mouse fibroblasts were used as mutational targets.
