First stage of cell division

Interphase is the process through which a cell must go before mitosis, meiosis, and cytokinesis. Interphase consists of three main phases: G1, S, and G2. G1 is a time of growth for the cell where specialized cellular functions occur in order to prepare the cell for DNA replication. There are checkpoints during interphase that allow the cell to either advance or halt further development. One of the ch… WebThey occur via four essential stages in early animal development: Fertilization: the process of a single sperm cell combining with single egg cell to form a zygote. Cleavage: rapid, multiple rounds of mitotic cell division where the overall size of the embryo does not increase. The developing embryo is called a blastula following completion of ...
