Vedclass · Answer

(C) Cleavage is a series of rapid mitotic divisions of the zygote that converts a single-celled zygote into a multicellular structure called a blastocyst.During cleavage,the total volume of the embryo remains constant,and the size of the zygote does not increase.As the number of cells (blastomeres) increases,the size of each individual cell decreases.However,the amount of $DNA$ per cell remains constant,and the total amount of $DNA$ in the embryo increases because each cell division is preceded by $DNA$ replication.Therefore,the amount of $DNA$ does not decrease; it increases.

Which of the following does $NOT$ occur during the process of cleavage?
