The enzyme telomerase uses mechanisms that involve:
A) Repeating sequences at the telomeres.
B) Having RNA oligonucleotides to act as templates as part of the enzyme.
C) Allowing the end of the chromosome to get a little shorter each time a cell divides.
D) Both repeating sequences at the end of chromosomes and RNA oligonucleotides to act as templates as part of the enzyme.
E) All of these.

Question

Quizplus · Accepted Answer

Telomerase uses an RNA template that is part of the enzyme to add repeating sequences to the ends of chromosomes, thus both A and B are correct. C is incorrect because telomerase actually prevents the shortening of telomeres during cell division.
