35. Which of the following is correct for the eukaryotic chromosomes?
(A) The ends of eukaryotic chromosomes are called telomeres, and contain special repeat sequences, called telomeric sequences.
(B) Telomere terminal transferase containing the reverse transcriptional activity is important to maintain the chromosomal ends in eukaryotes.
(C) The centromeric sequences are important for proper chromosome segregation during replication.
(D) Kinetochores assemble at the centrosome.
(E) Telomerase activity declines with age and this could explain why cells lose their ability to divide after many replications.
