For this reason it is generally absent from body tissues in adults. Bone marrow is an exception to this rule, however, since even in adults, bone marrow cells continually divide to replace old blood cells. Cancers are another exception, because their cells are rapidly dividing.

Option (D).

Explanation:

Telomerase enzyme is necessary for the replication of telomeres. This enzymes are also known as terminal transferase and made of ribonucleoprotein.

The increased telomerase activity is the common characteristics of the cancer cell that distinguish them from the normal cells. The cancer cells divide continuously and require the telomerase activity for the end replication of the DNA.

Thus, the correct answer is option (D).

a. True.

Explanation:

Even though the cells in our body rely on glucose as a source of energy, they can replace glucose's energy with lipids or proteins' energy. In the brain's case, this is not possible since the blood-brain barrier, which is a highly selective barrier between the blood and the extracellular fluid in the central nervous system, allows the passage of glucose as the only source of energy. This is why maintaining the correct levels of glucose is crucial for the metabolism in the brain.

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.

Question: Telomerase is an enzyme that is produced only in cells that are actively dividing. For this reason it is generally absent from body tissues in adults. Bone marrow is an exception to this rule, however, since even in adults, bone marrow cells continually divide to replace old blood cells. Cancers are another exception, because their cells are rapidly dividing.

The information provided most strongly supports which of the following?

A. Telomerase is the only enzyme that is present in cancerous cells but absent from cells that are not actively dividing.

B. In children, the only body tissues from which telomerase is absent are those in which cells are not rapidly dividing.

C. The presence of telomerase in bone marrow is no indication of bone marrow cancer.

D. Cancer of the bone marrow develops more rapidly than cancer growing in any other kind of adult tissue.

E. The level of telomerase production is always higher in cancerous tissue than in noncancerous tissue.

Bone marrow is an exception to this rule, however, since even in adults, bone marrow cells continually divide to replace old blood cells. Cancers are another exception, because their cells are rapidly dividing. The presence of the telomerase in bone marrow is no indication of bone marrow cancer.

Explanation:

The presence of the telomerase in the bone marrow is not the indication of the bone marrow cancer because as we know in the bone marrow cells they telomerase naturally. For the survival of the cancer cells presence of protein complex at the end of the chromosomes are ought to be necessary. These are maintained by an enzyme called as telomerase. So basically telomerase are the enzymes, present in the large numbers in majority of the tumors. These telomerase act as protectants from the chromosomes getting fusion and also from being recognized as sites of DNA damage.
