• B. They break down the nuclear membrane
• C. They help in the duplication of the DNA
• D. They make the chromosomes visible

Answer 1

The correct option is A They help to separate the chromosomes

Mitotic spindle is assembled by centrosomes. Mitotic spindle, present at the poles of the cells, is a structure made of microtubules (spindle fibres). Its role is to separate the chromosomes. The spindle fibres attach to chromosomes during metaphase and pull the chromatids towards opposite poles during anaphase.
