Question

Under the microscope, a cell shows formation of centrosomes and spindle microtubules. What will happen next?

Answer 1

The chromosomes will divide along the centrosomes and move to opposite poles

Answer 2

Answer:

The correct answer will be chromosomes will separate and reach opposite poles.

Explanation:

In animal cells during prophase of M-phase, centrosomes- an organelle containing centrioles appear near the nucleus which moves to the opposite poles from which spindle fibres develop.

These spindle fibres attach to the kinetochore of chromosomes during metaphase when they are present at the equator. During anaphase, theses spindle fibres pull apart the chromosomes causing separation of the chromosomes and chromosomes reaches opposite poles.

Thus, chromosomes will separate and reach opposite poles is the correct answer.
