dna methylation based biomarkers and the epigenetic clock theory of ageing

Despite the fact that biomarkers of ageing based on dna methylation data have enabled accurate age estimates for any tissue across the entire life course the. The programmed theory of aging suggests that aging is tightly regulated similar to a biological clock and contains subcategories. In a recent breakthrough biomarkers of ageing based on dna methylation data have enabled accurate age estimates for any tissue across the entire life course.
