into the cells. It is here we find a direct connection between what you eat and the health of trillions of cells that make up the human body. Each person begins as a single cell -- a cell structure formed by the joining of the mother's egg and the father's sperm. That single cell contains the digital code to make thousands of other kinds of cells, from fat cells to bone cells -- from brain cells to lung cells. There are muscle cells, skin cells, vein cells, capillary cells and blood cells… Ultimately

This phase is generally the longest of the four cell cycle phases and is quite variable in length. During this phase, the cell chooses either to replicate its deoxyribonucleic acid (DNA) or to exit the cell cycle and enter a quiescent state (the G0 phase). S phase Replication
