Resumo de Recurso

AQA AS Biology Cell Cycle
  1. 1. Interphase
    1. G1
      1. New cell grows and carries out normal functions
      2. S Phase
        1. The cell's DNA is replicated - each chromosome becomes double stranded
        2. G2
          1. The second growth phase
        3. 2. Prophase
          1. Nuclear envelope and nucleus disappears
            1. Chromosomes condense and become visible under a microscope
            2. 3. Metaphase
              1. Spindle fibres form
                1. Chromosomes line up at the cell equator
                2. 4. Anaphase
                  1. Spindle fibres attach to the centromere of the chromosomes
                    1. Sister chromatids are pulled to opposite poles of the cell
                    2. 5. Telophase
                      1. Cytokinesis begins
                        1. Nucleolus and nuclear envelope reforms
                          1. Chromosomes become invisible under a microscope
