Question: Stem cells located in the gastrointestinal tract would possess more active telomerase compared to the amount of telomerase activity in mature neurons of the brain. (T/F)

Answer:

True

Step-by-step explanation:

Telomerase is the enzyme responsible for replication of ends of the linear chromosomes as DNA polymerase cannot replicate them in the absence of primer. The stem cells in the gastrointestinal tract divide repeatedly to replace the wear and tear cells. Therefore, these cells have active telomerase to replenish the chromosomal ends during each DNA replication. On the other hand, mature neurons are the differentiated cells that do not divide after maturity. Therefore, they lack the active telomerase.
