WebMitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. Some textbooks list five, breaking prophase into an early phase (called prophase) and a late phase (called prometaphase). These phases occur in strict sequential order, and cytokinesis - the process of dividing the cell contents to make two new cells - starts ...

WebThe three stages of interphase are called G1, S, and G2. G 1 Phase (First Gap) The first stage of interphase is called the G1 phase (first gap) because, from a microscopic point of view, little change is visible. However, during the G 1 stage, the cell is quite active at the biochemical level. WebThe four stages of mitosis were observed in the blastula staged whitefish embryo slides. The phases of mitosis are prophase, metaphase, anaphase, and telophase. The beginning stages that occur in mitosis take place in interphase, which are G_1, S, and G_2. In the G_1 stage, the cell begins to increase in size. After the size of the cell has ...
