what is biolocal ageing
Also known as epigenetic clock, DNA clock, Horvath's clock or DNA methylation age, this biological aging clock is an age predictor that can be used to measure the age of most human tissues, cell types, or organs.orvath hypothesized that DNA methylation age measures the cumulative effect of an epigenetic maintenance system but details are unknown. The fact that DNA methylation age of blood predicts all-cause mortality in later life suggests that it relates to a process that causes aging.
