Telomerase is an enzyme that is produced only in cells that are actively dividing. For this reason it is generally absent from b

ody 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.

Answer:

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).

elena-14-01-66 [18.8K]

Answer:

50 %

Explanation:

It is given that a woman gives birth to a baby boy. Her second child is also a baby boy. Now she is about to give birth to her third child. We have to determine the probability of the child to be a girl.

Here, the probability of the child to be a girl would be 50 % or 1 out of 2.

There are two possibilities and the possibilities would result a boy child or a girl child. So there are two possible outcomes and is equally likely with each child birth.

Also each child birth is an independent event, so the probability that the one results will occur do not depend on the previous births.
