... 7 The natural incidence of mutations is increased by mutagens. Mutations may be concentrated at hotspots. A type of hotspot responsible for some point mutations is caused by deamination of the modified base 5-methylcytosine. 8 Forward mutations occur at a rate of ~10 6 per locus per generation; bac ...
