Computational epigenetics is the use of computer technology to study the epigenome -- the part of our DNA that controls how our genes are expressed (which traits we have and how active those traits are). The epigenome is made up of different chemicals that attach themselves to areas of DNA, telling our bodies what to do with the information stored in it. Computational epigenetics is used to study how these chemicals interact to shape who we are and how our bodies function. Scientists use computers to analyze large amounts of data, look for patterns and make predictions about how different combinations of epigenetic chemicals affect our health and development.
