Question

Prophase-l is divided into five phases based on
(A) time duration
(B) crossing over patterns
(C) chromosome behavior
(D) None of these​

Answer 1

Changes in microtube length provide the mechanism for chromosome movement. More specifically in the first part of anaphase-sometimes called anaphase A-the kinetochore microtubules shorten and draw the chromosomes toward the spindle poles.

So, the correct option is 'Chromosomal movement'.
