Centromere is required for:

1. movement of chromosomes towards poles
2. cytoplasmic cleavage

Correct answer: movement of chromosomes towards poles

Solution

The centromere is the chromosome region where the kinetochore forms and spindle fibers attach, allowing sister chromatids or chromosomes to be pulled to opposite poles. It is not involved in cleavage, crossing over, or transcription.
