WebGenerally speaking, there were just about as many epigenetic changes in Scott as there were in his twin. The biggest difference was observed nine months into Scott's space mission when 79 percent of his DNA was methylated (when methyl is added to DNA), compared to 83 percent of Mark's DNA. WebMay 17, 2024 · epigenetic An adjective that relates to the molecular switches that can turn a gene on or off. Methyl groups — chemical clusters each made of one carbon and three hydrogen atoms — latch onto DNA near a gene. It’s these methyl groups that can alter the programmed activity of a gene.
