How much information could possibly be in our DNA. Science is such an amazing creation that surprises us everyday. it it said that every little bit of our makeup is written in our DNA. This information includes, personality traits, physical body traits, and many many more. It is said that our DNA is capable of storing 215 petabytes in just one single gram of DNA. This is a crazy about of room to store our genes. Whats even more crazier is that our DNA is made up as we a little baby before we are even born. It is made up from the genes coming from a person's parents. People really do underestimate the strength our DNA has and what it can hold.
