17 February 2019 P 30 Read pp. 250-252 Answer Q. 1-5 p. 252 P 31 Cancer: Uncontrolled Cell Growth

Uncontrolled Cell Growth Cancer Uncontrolled Cell Growth

Cancer is a disorder in which some cells have lost the ability to control their growth rate.

Factors that regulate the cell cycle: Cyclins Proteins that regulate the internal timing of cell cycle For example can cause the mitotic spindle to form Growth factors External regulator proteins that stimulate the growth and division of the cell Especially important during embryonic development and wound healing P53 Gene that halts cell cycle until all chromosomes have been replicated

When healthy cells come in contact with other cells they stop growing.

Cancer cells continue to grow and divide when then touch other cells Cancer cells continue to grow and divide when then touch other cells. This causes tumors and metastasis.
