Theoretical physicists have confirmed that it's not just the information coded in our DNA that shapes who we are—it's also the way DNA folds itself that controls which genes are expressed inside our bodies.
We all learned in high school how Watson and Crick pieced together the findings of many scientists to come up with a model of deoxyribonucleic acid (DNA). Information in DNA is stored as code sequences made up of nitrogenous bases. Each cell has the same sequence of codes but executes a different function. Code sequences determine the type of protein to be produced in a certain cell, but it is hypothesized that the mechanical properties of the DNA acts as a second layer of information.
Each cell in our body contains around 2 meters of DNA. But since our cells are so tiny, DNA strands have to be tightly wrapped into bundles called nucleosomes in order to fit.
