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

Options

  1. Aare RNA transcription initiator
  2. Bhelp chromosome pairing
  3. Cprevent chromosome loss
  4. Dact as replicons.

Correct answer

C. prevent chromosome loss

Step-by-step solution

The terminal end of the chromosome is known as a telomere. It consists of repetitive DNA sequences. These are stable and resistant to exonuclease digestion and hence essential for chromosome stability.
