Anaphase-The third stage of mitosis

Tuesday, July 14, 2020

Anaphase is the third stage of mitosis.

Here is what anaphase looks like in real life.

Anaphase is the shortest stage of mitosis and accounts for only roughly 1 % of mitosis.

During metaphase, the chromosomes have been aligned in the middle of the cell and spindle fibers have attached to each  Sister chromatids at the kinetochore.

In anaphase, the sister chromatids separate from each other and are pulled towards opposite ends of the cell.

The protein “glue” that holds the sister chromatids together is broken down, allowing them to separate. Each is now its own chromosome. The chromosomes of each pair are pulled towards opposite ends of the cell.

Microtubules not attached to chromosomes elongate and push apart, separating the poles and making the cell longer.

From anaphase, the cell moves to telophase.
