WebMutational signatures can leave their mark in the form of differential mutational frequencies between the two DNA regions: genic regions and intergenic regions. The upper bar plot represents the percentage of real mutations in genic and intergenic regions averaged across the human genome as well as all examined samples in 96 mutational context. WebThe mutations arising due to exogenous factors accumulate over time independent of cell cycle events. Grasping the etiologies of clock-like signatures can provide an important foundation for studying cancer evolution, as these provide a direct measure of the genomic timescale of exposure.
