What are rigorous assays to measure the impact of a given enzyme and its inctivation on mutation rates, patterns, and signatures?

07 July 2018 0 2K Report

I am intersted in measuring the impact of specific enzymes and their inactivating mutations on genome instability and on the mutation burden in human cells and cancers. I want experiment ways to measure causitive relationships between DNA repair proteins and the degree and types of instability.
