Smoking, a leading preventable cause of deaths worldwide, impacts the human DNA for more than 30 years even after one quits, a study has found. The findings showed that smoking leaves its “footprint” on the human genome in the form of DNA methylation — a process by which cells control gene activity. Methylation, one of the mechanisms of the regulation of gene expression, affects what genes are turned on, which has implications for the development of smoking-related diseases. “Our study has found compelling evidence that smoking has a long-lasting impact…
