12. What do genes do? They tell cells what to do
13. Mom tells Richie: Genes are the set of chemical instructions that get passed down from Parent to child. In the process, of course, the genetic material is recombined in new ways, which is why some people bear resemblance to their Parents and Grandparents without looking like any one relative in particular.
