Question

What is the difference between Anaphase, Anaphase 1, and Anaphase 2?

Answer 1

Anaphase:

1. Following the metaphase procedure, the mitotic stage known as anaphase takes place.
2. During this time, the replicated chromosomes are split, and the newly copied chromosomes are transferred to the opposing poles of the cell.

Anaphase 1:

The chromosomes migrate in opposing directions during the third stage of meiosis 1, known as anaphase 1, with the assistance of their kinetochores, which are guided by microtubules or spindle fibers.

Anaphase 2:

1. Anaphase 2 is the third stage of meiosis 2.
2. It occurs after metaphase 2 when the chromosomes are in the equatorial plane, and the spindle fibers are connected to the kinetochores.
3. The sister chromatids of each chromosome separate and travel toward the opposing poles due to the shortening of kinetochore microtubules.
4. Anaphase 2 is followed by telophase 2.

,

S.no	Anaphase	Anaphase I	Anaphase II
1.	It takes place during mitosis.	It takes place during meiosis I	It takes place during meiosis II
2.	The splitting of centromere separates the chromatids.	The sister chromatids remain associated at their centromere.	Two sister chromatids are separated by splitting the centromere
3.	The chromosomes move to opposite poles.	Homologous chromosomes move to opposite poles.	Sister chromatids move to opposite poles.
