If you were able to find a drug that could inhibit the reactivation of telomerase activity in cancer cells, the cancer cells would: eventually die from lack of energy. gradually revert to normal cells. slowly erode their chromosome ends. stop dividing immediately. become less invasive.

The right answer is slowly erode their chromosome ends.

Telomerase is an enzyme found in eukaryotic organisms, which, during DNA replication, has the mission to dress the telomere chromosomes, nucleotide sequences placed at their ends and used to preserve them.

Telomerase expresses itself very little (if at all) in differentiated cells. By dint of cellular divisions, the telomeres disappear, the chromosomes are damaged and the cell returns to senescence. In contrast, the enzyme is very active in germ lines. It therefore prevents aging stem cells. It is considered that it could be one of the levers to activate to curb or even stop aging.

humans, along with other animals and plants, have linear chromosomes that are arranged in pairs within the nucleus of the cell. the only human cells that do not contain pairs of chromosomes are reproductive cells, or gametes, which carry just one copy of each chromosome.

from my research i have to the conclusion that decomposers, such as fungi, bacteria and invertebrates, play a critical role in nutrient cycling and without them the earth's ecosystem may not support life as we know it. elements such as carbon, nitrogen and phosphorus exist in limited amounts on earth, although huge amounts of carbon are being released into the atmosphere from underground sources now by humans. it is still extremely important that other nutrients be retained by the process of re-use. decomposers are organisms that are able to chemically break down dead material and make these elements available for use by other organisms. without this breakdown of dead material, dead bodies would pile up. so decomposers also play a role in clean up also. without them, life might not continue as we know it and dead material would overwhelm the earth.
