Question

The separation of two chromatids of each chromosome at early anaphase is initiated by

• A. The interaction of centromere with the chromosomal fibres.
• B. The elongation of metaphasic spindle
• C. The force of repulsion between the dividend kinetochores
• D. All of the above

Answer 1

Answer: (C)

The force of repulsion between the dividend kinetochores

• Anaphase is the stage of mitosis after the metaphase when replicated chromosomes are split and the daughter chromatids are moved to opposite poles of the cell.
• The separation of two chromatids of each chromosome at early anaphase is initiated by the force of repulsion between the divided kinetochores.
• Kinetochores are a protein that forms a complex with the centromere of a chromosome during cell division.

So, the correct answer is option C.
