Meiosis is a specific type of cell division that occur in the germ cells.Meiosis is called reductional division because the 4 new cells those are produced after second meiotic division contain half the number of chromosomes as that of original cells.
During meiosis a cell undergo division two times the division that occur during first time is called first meiotic division resulting in the formation of 2 cells having 2n number of chromosomes.On the other hand the second meiotic division form 4 cells each having half the number of chromosomes.

This change in the shape of the enzyme can affect its activity, since it can change the active site consequently to this conformational change.
