A population of cells was exposed to UV radiation for 10 minutes. A sample of the mutagenized cells was plated on complete media, and 200 colonies formed. These 200 colonies were replica plated to minimal media, and 17 colonies grew. When the 200 colonies were replica plated to complete media missing biotin, only 40 colonies grew. What was the biotin mutation rate in this experiment
