topic 1.6:  cell division


Essential Ideas:
  • Cell division is essential but must be controlled.
  • Problems with cell division control can result in diseases such as cancer.

Cell division process and functions
​

1.6U1:  Mitosis is division of the nucleus into two genetically identical daughter nucleii.
1.6U2:  Chromosomes condense by supercoiling during mitosis.
1.6U3:   Cytokinesis occurs after mitosis and is different in plant and animal cells.
1.6U4:   Interphase is a very active phase of the cell cycle with many processes occurring in the nucleus and cytoplasm


1.6Skill1:  Identification of the phases of mitosis viewed with a microscope or in a micrograph..

Cell Cycle Regulation
​

1.6U5:  Cyclins are involved in the control of the cell cycle.
1.6U6:  Mutagens, oncogenes, and metastasis are involved in the development of primary and secondary tumours.

1.6A1:  The correlation between smoking and the incidence of cancers.

1.6Skill2:  Determination of the mitotic index from a micrograph.
LIfe is wonderfully complicated.   Stay curious.  Be skeptical.    And above all, ask many questions!
