5.3 regulation of the cell cycle study guide answers

Internal and external factors regulate cell division. Malignant tumors have cells that break away, or metastasize, and spread to other parts of the body, forming new tumors. External factors include physical and chemical signals. Standard cancer treatments typically kill both cancerous and healthy cells. Cancer cells can arise from normal cells that have experienced damage to their genes involved in cell cycle regulation. Cancer cells do not carry out necessary functions. Damage may arise from inherited errors in genes, from mutations carried by viruses, and from carcinogens.

Although these are often referred to as inherited cancers, what is inherited is the abnormal gene that can lead to cancer, not the cancer itself. Growth factors are proteins that stimulate cells to divide. Neither you, nor the coeditors you shared it with will be able to recover it again. Mutations in sex cells, or gametes, do not affect the individual. Cyclins and kinases are two of the most important internal growth factors.

Radiation therapy and chemotherapy are common treatments for cancer. Carcinogens are substances known to produce or promote the development of cancer. Very often, an external factor triggers the activation of an internal factor. External factors trigger internal factors, which affect the cell cycle. These include substances such as tobacco smoke and other air pollutants. It activates kinases, which in turn, add a phosphate group to other molecules that help drive the cell cycle forward. Most cells respond to a combination of growth factors, not just one.

But mutations in gametes can cause chromosomal abnormalities in their offspring. A cyclin is a type of internal factor. Some forms of cancer have been shown to be hereditary, such as breast cancer and colon cancer. Internal factors come from inside the cell. Cell division is uncontrolled in cancer. Apoptosis is programmed cell death. These include cell—cell contact, which prevents further growth of normal cells, and chemical signals called growth factors.

Some growth factors affect many different types of cells. Malignant tumors are more difficult to treat than benign tumors. Only about 5% to 10% of all cancers are inherited. . Cancer cells can continue to divide despite cell—cell contact or a lack of growth factors.
