  • Cell Differentiation
    • Stem cells all contain the same genes, but not all of them are expressed because not all of them are active.
      • Under the right conditions, some genes are activated, and other genes inactivated.
        • mRNA is only transcribed from the active genes.
          • The mRNA from the active genes is then translated into proteins.
            • These proteins modify the cell- they determine the cell structure and control  cell processes.
              • Changes in the cell produced by these proteins cause the cell to become specialised (differentiate). These changes are difficult to reverse, so once a cell has differentiated it stays specialised.
