Question

What happens during the metaphase of cell division?

A) Chromosomes uncoil
B) Centrioles move to poles of the cell
C) Chromosomes line up across the center of the cell
D) Nuclear membrane reappears

Answer 1

In the metaphase of cell division, c. chromosomes line up across the center of the cell, or the metaphase plate, preparing for their eventual separation into two new cells.

Step-by-step explanation:

During the metaphase of cell division, the key event is when the chromosomes line up across the center of the cell, which is sometimes referred to as the metaphase plate or the cell's equator. The spindle fibers, which are composed of microtubules, attach to the centromeres of each chromosome, and the sister chromatids align in preparation for their separation.

This phase ensures that each new cell will receive an identical and complete set of chromosomes during cell division. The correct answer to the student's question is C) Chromosomes line up across the center of the cell.
