What is the key event that occurs at the onset of anaphase?
What is the key event that occurs at the onset of anaphase?
Chromosomes are moved to spindle equator
Centromeres split and chromatids separate
Chromosomes are aligned along metaphase plate
Spindle fibres attach to kinetochores of chromosomes
Solution
At the onset of anaphase, each chromosome arranged at the metaphase plate is split simultaneously and the two daughter chromatids, now referred to as daughter chromosomes of the future daughter nuclei, begin their migration towards the two opposite poles.
