"Mutation frequencies" refers to how often changes occur in the genetic material of living organisms. It measures the rate at which mutations or alterations happen within the DNA sequence of genes. Full definition
This way the researchers obtain data for each type of mutation as well as precise mutation frequencies at any position of the RNA. (sciencedaily.com)
This approach not only validates mutations, but also measures the precise mutation frequencies of thousands of cells.» (sciencedaily.com)
Another interesting application of massively parallel sequencing was the estimation of mutation frequencies in the tumor sample using the Roche / 454 platform. (massgenomics.org)
