Why therapy that rebuilds the telomeres would not be a good way to achieve “eternal youth”.

Introduction:

The shortening of the telomere at each cycle of DNA replication is one of the factors that lead to cell death.

Expert Solution & Answer

Explanation of Solution

Cell death is very much a part of the natural functioning of a multicellular organism. This, however, leads to aging. It is known that the shortening of the telomeres of a chromosome beyond a certain point leads to cell death. However, if an attempt is made to maintain the length of telomeres by rebuilding them, the cells can turn cancerous. People who undergo such a therapy will have increased risk of cancer.

Conclusion

Rebuilding of the telomeres can make the cells become cancerous. this kind of therapy increases the risk of death by cancer. Therefore, it is not a good solution to the quest for “eternal youth”.

Part A Telomere shortening puts a limit on the number of times a cell can divide. Research has shown that telomerase can extend the life span of cultured human cells. How might adding telomerase affect cellular aging? Telomerase eliminates telomere shortening and retards aging. Telomerase would have no effect on cellular aging. Telomerase shortens telomeres, which delays cellular aging. Telomerase will speed up the rate of cell proliferation. Submit Request Answer

Human cells divide every day for normal growth, replacement of cells, and tissue repair. The dividing cells proceed through the three phases of the cell cycle as shown in the figure. When a person experiences a cut, damaged skin cells secrete a protein called epidermal growth factor (EGF). Epidermal (skin) cells in the vicinity of the injury possess proteins in their cell membranes called epidermal growth factor receptors (EGFR) Cancer can result from disruptions in cell cycle control. Mutations that increase the production of EGFR have been associated with skin cancer of the head and neck. Describe how a mutation outside of the coding region of a gene that encodes EGFR could lead to the overproduction of EGFR protein in a skin cell.

Describe what a telomere is, and explain its role in cancer cells’ unlimited ability to divide.
