Understanding Metaphase in Mitosis

This video from Mumu Math and Science explains metaphase, the second stage of mitosis. During metaphase, chromosomes align in the middle of the cell, facilitated by microtubular fibers that attach to the chromosomes at the centromeres. These fibers extend from the cell poles and help position the chromosomes for the next stage, anaphase. The video concludes with a summary and encourages viewers to subscribe for daily math and science content.

What is the second stage of mitosis called?

• Prophase

• Metaphase

• Anaphase

• Telophase

During metaphase, where do the chromosomes align?

• In the nucleus

• At the poles of the cell

• In the middle of the cell

• Outside the cell

What structures attach to the chromosomes during metaphase?

• Mitochondria

• Ribosomes

• Cell membranes

• Microtubular fibers

What is the specialized region where microtubular fibers attach to chromosomes called?

• Centrosome

• Nucleolus

• Connector core

• Cytoplasm

What is the next stage after metaphase in mitosis?

• Telophase

• Anaphase

• Prophase

• Interphase

What is the main role of spindle fibers during metaphase?

• To replicate DNA

• To form the cell membrane

• To divide the cell

• To align chromosomes in the middle
