Identify the primary constriction on the chromosome?
1 Centromere
2 Centrosome
3 Kinetochores
4 Spindle fibres
Explanation:
Every chromosome (visible only in dividing cells) essentially has a primary constriction or the centromere. Centromere holds two chromatids of a chromosome.

Two unequal arms are present in
1 Metacentric and submetacentric chromosomes
2 Submetacentric and acrocentric chromosomes
3 Acrocentric and metacentric chromosomes
4 Telocentric and metacentric chromosomes
Explanation:
In metacentric chromosome the two arms are equal whereas in telocentric there is one arm.

The function of nuclear pore is
1 For movement of RNA molecules in both directions between the nucleus and the cytoplasm.
2 For movement of protein molecules in both directions between the nucleus and the cytoplasm.
3 For movement of RNA and protein molecules in one directions between the nucleus and the cytoplasm.
4 For movement of RNA and protein molecules in both directions between the nucleus and the cytoplasm.
Explanation:
The function of nuclear pore is for movement of RNA and protein molecules in both directions between the nucleus and the cytoplasm.
