How DNA Reveals Your True Age! Video Watch time Under 1 minute January 8, 2025 Image Can your genes tell you how old you are? In this video, Alex Dainis explains how telomeres and histones are both DNA signatures that can be used to determine age! Telomeres are protective repeating segments at the end of your DNA that get shorter every time cells in your body divide. Your telomeres are longer when you’re younger, and shorter when you’re older. Histones are proteins that DNA winds around in your cells, and they have molecular tags on them that change as you age. Studying these two genetic markers allows scientists to better understand disease, longevity, and how therapeutics might be able to change the genetic age of your cells!
