If you were to exam the genetic make-up of one of your liver cells and one of your heart cells, how would they
compare?
You started out as a tiny fertilized egg – a single cell. How did that single cell get to be the many cells that
make you and how did those cells become all the different cells (like liver and heart cells) that perform
specific functions in your body?
