Telomere repetitive DNA sequences control the function of eukaryotic chromosomes because they

  • act as replicons.

  • are RNA transcription initiator

  • help chromosome pairing

  • prevent chromosome loss

Solution

D.

prevent chromosome loss

Telomeres are ends of a chromosome, have repetitive DNA sequences and are stable and resistant to exonuclease digestion hence, essential for chromosome stability.
