Question

Structure made of fibers that help to move chromosomes during mitosis are called

Answer 1

Answer: spindle

Explanation: A spindle is a structure made up of fibers which are long strands of proteins. Spindles organize and move the chromosomes apart to each side of the cell during mitosis so that the chromosomes will be evenly distributed between the two daughter cells allowing them to be totally identical. Spindle formation starts during the prophase stage in mitosis, and in metaphase chromosomes are aligned in the middle of the cell by the spindle. In Anaphase, the chromosomes separate and are moved to the spindle poles.

Answer 2

Spindle

Step-by-step explanation:

Spindle is the structure which is made up of strong fibers called microtubules. They help in moving the chromosome towards the pole so that the chromosomes can be evenly distributed in the daughter cells.

Spindle fibers are generated in both mitosis and meiosis. In mitosis, it is called mitotic spindle and in meiotic cell division, it is called meiotic spindle. These spindle fibers start originating in prophase of the cell cycle. In anaphase, the spindle fiber separates the chromosome.
