Telomerase is a(an)
A)constriction that determine the shape of chromosomes during cell division.
B)sequence of nucleotides that code for proteins which function as enzymes.
C)sequence of nucleotides that code for proteins which function as chemical messengers,usually hormones or neurotransmitters.
D)enzyme which adds specific groups of nucleic acids to the ends of the DNA molecule.
E)sequence of non-coding nucleotides at the ends of chromosomes.

Question

Quizplus · Accepted Answer

Telomerase is an enzyme that adds specific groups of nucleic acids (telomeres) to the ends of the DNA molecule, which helps protect the integrity of the genetic material during cell division. Option A is incorrect as it describes centromeres, not telomerase. Option B is incorrect as it describes genes, not telomerase. Option C is incorrect as it describes the function of certain proteins, not telomerase. Option E is partially correct but incomplete as it only describes the non-coding sequence at the ends of chromosomes, not the enzyme that adds these sequences.
