Mitosis & the cell cycle

  • describe the structure of a chromosome, limited to DNA, histone proteins, chromatids, centromere and telomeres
  • explain the importance of mitosis in the production of genetically identical cells, growth, cell replacement, repair of tissues and asexual reproduction
  • outline the cell cycle, including interphase (growth and DNA replication), mitosis and cytokinesis
  • outline the significance of telomeres in permitting continued replication and preventing the loss of genes
  • outline the significance of mitosis in cell replacement and tissue repair by stem cells and state that uncontrolled cell division can result in the formation of a tumour
  • describe, with the aid of photomicrographs and diagrams, the behaviour of chromosomes in plant and animal cells during the mitotic cell cycle and the associated behaviour of the nuclear envelope, cell surface membrane and the spindle (names of the main stages of mitosis are expected)
  • describe the process of binary fission in prokaryotes
