When we’re born, our genes click on and whir away to produce our personalities, diseases and physical appearances. Or do they? Research has now revealed that genes can turn on and off; they can be expressed for years and then silenced, or never even used. And what controls them? Scientists have recently discovered our epigenome, biological markers along our DNA that regulate gene expression in response to features like age or environment, and which can influence the traits we pass onto our children. Join a glimpse of the future with scientists at the forefront of the emerging field of epigenetics as they reveal the role our genetic markers play in steering our biological destiny.
