A sample of book….
The Nucleus is the center of a cell. A cell is located in ,well, EVERYWHERE!!!!!!!! Have you ever wondered how you fight off diseases, or why your blood is red,because the answers would be:white blood cells;red blood cells. The reason I was talking about proteins is because proteins take copies of DNA,called RNA which tells the protein maker to form proteins and then the proteins form cells,which form muscles or hearts or lungs, which form up animals.So just because you can’t SEE these cells with the naked eye, doesn’t mean they aren’t there. There are also lung cells, heart cells, bone cells… And a lot of other cells.Blood cells in your body are mostly red, so that is why your blood is red.
