Answer: True
Explanation:
Telomerase is an enzyme that is produced in the body. It prevents the shortening of the length of telomeres.
Telomerase is not usually activated in the cells of the body but you can find them in cells responsible for the production of sperm and egg in humans.
In others for cells to keep living , the length of the telomere must be maintained and this is one of the reasons why cancer cells thrives in the body and keeps dividing and spreading because telomeres are always present in cells that keep dividing.
Telomere are very essential to growth of cancerous cells. Shortening the length of telomeres is not enough to kill cancerous cells as we have cancer cells with short length ( bone, kidney, prostate cancer). We have to combine other methods of cancer treatment to be able to eradicate the cancerous cells from the body.
Bone marrow is a body tissue where the cells are always dividing because this is crucial and essential for the replacement of old cells. In the bone marrow we can find enzyme telomerase present hence, this makes the bone marrow an exception.
