Understanding Anaphase in Mitosis

This video tutorial from Moomoomath explains anaphase, the third stage of mitosis. Anaphase is the shortest stage, accounting for about 1% of mitosis. During this stage, sister chromatids separate and move to opposite ends of the cell. The protein glue holding them together breaks down, allowing separation. Microtubules elongate, pushing cell poles apart and lengthening the cell. The video concludes with a transition to telophase, the next stage of mitosis.

What is the significance of anaphase in the process of mitosis?

• It is the longest stage of mitosis.

• It is the stage where the cell divides into two.

• It is the stage where DNA replication occurs.

• It is the shortest stage and involves chromosome separation.

During anaphase, what happens to the sister chromatids?

• They separate and move to opposite ends of the cell.

• They are replicated.

• They remain attached at the center of the cell.

• They dissolve into the cytoplasm.

What role do spindle fibers play during anaphase?

• They dissolve the nuclear membrane.

• They provide energy for cell division.

• They attach to chromosomes and help in their separation.

• They help in DNA replication.

What is the function of the protein glue during anaphase?

• It provides energy for cell division.

• It forms the nuclear membrane.

• It helps in DNA replication.

• It holds sister chromatids together until they separate.

What happens to the microtubules not attached to chromosomes during anaphase?

• They shorten and pull the cell together.

• They elongate and push the cell apart.

• They attach to the nuclear membrane.

• They dissolve into the cytoplasm.

What is the next stage after anaphase in mitosis?

• Telophase

• Cytokinesis

• Metaphase

• Prophase
