Biological Spell Check...
a: Dna polymerase ~
b: a word processor
What: "You need to have a way to fix mistakes., or a proofreading capacity. Each of your cells has 46 DNA moleucles, about 6 billion bases. It only takes a few hours to copy all of this with very few errors. The DNA polymerase is like a word processor. When it sees a mistake it will back up and fix it like hitting the delete key on a computer."
