Homework Answers
Answer of the questions is option ' C ' or 'D' the option is not visible in the last word so the answer is One of them . Just check last word of the option C and D which have written the cell division .
So the correct answer is - Mitotic spindle is composed of microtubules and associated protein .it helps pull chromosomes to opposite ends of a dividing cell during cell division .
Because , mitotic spindle consists of fibers made of microtubules and associated proteins. And it helps pull chromosomes to opposite ends of a dividing cell during cell division .
Please rate the answer . It's a lot of matters to me . ?
Good luck have a nice day .

During the M-phase (Mitosis), spindle fibers extend from centrioles in the poles of the cell and attach to the centromeres of each replicated chromosome. The chromosomes are aligned along the equatorial plate of the cell in the process. Once all centromeres got attached from either side to a spindle fibre, a cellular checkpoint got passed and the spindle fibers begin to contract towards the poles, pulling the two sister chromatids apart such that one sister chromatid of each of the...
