Question

Telomere has a unique property of ................

• A. condensation of chromatin network.
• B. prevention of ends of the chromosomes from sticking together.
• C. attaching to spindle fibres.
• D. regulation of protein synthesis.

Hint:

Telomeres protect chromosome ends, preventing the DNA from sticking together or degrading during cell division.

Answer 1

The Correct Option is B

Step 1: Understanding the role of telomeres.
Telomeres are repetitive sequences at the ends of chromosomes that protect the chromosome from degradation and prevent them from sticking together during cell division.
Step 2: Analyzing the options.
(A) condensation of chromatin network: Incorrect, this is not a property of telomeres.
(B) prevention of ends of the chromosomes from sticking together: Correct, this is one of the key roles of telomeres, ensuring chromosomes remain intact during division.
(C) attaching to spindle fibres: Incorrect, telomeres do not play a role in attaching chromosomes to the spindle fibres.
(D) regulation of protein synthesis: Incorrect, telomeres are not involved in protein synthesis.
Step 3: Conclusion.
The correct answer is (B) prevention of ends of the chromosomes from sticking together.
