Q169 / 200 · NEET 2007 · Zoology

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

A
are RNA transcription initiator
B
help chromosome pairing
Correct answer
C
prevent chromosome loss
D
act as replicons.

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.

Hence, the correct answer is option: 'C'.
