I was surprised to find out that red blood cells do not contain DNA. Every single part of your body contains DNA, except for red blood cells. It's funny, I would've thought that red blood cells would have DNA in them, because in a lot of crime and investigation tv shows the people use the bad persons blood to figure out stuff about them...I think. Either way I was very surprised because I would've thought that would be one of the parts of your body that would most likely have DNA in it.
The final, and most fascinating face that I now know is that a fast typist, working eight hours a day, would take 50 years to type out the human genome. 50 YEARS! That's absolutely crazy! It's truly amazing that our cells are copying any multiplying at a crazy rate, and every time they multiply themselves they have to copy the code perfectly every single time. Our cells do it almost perfectly throughout our whole lives.
