What is mitosis describe various stages of mitosis?
Mitosis has four stages: prophase, metaphase, anaphase, and telophase. Encyclopædia Britannica, Inc. mitosis, a process of cell duplication, or reproduction, during which one cell gives rise to two genetically identical daughter cells.
Which sequence of stages in mitosis is correct?
The correct answer is (b) prophase, prometaphase, metaphase, anaphase, telophase.
What is the correct sequence of a cell cycle?
The cell cycle comprises two phases, i.e. interphase and mitosis or M phase. Interphase is further divided into three phases, G1, S and G2. Hence the correct order of stages in the cell is G1 → S → G2 → M.
What are all the stages of the cell cycle?
Phases of the Cell Cycle The cell cycle is a 4-stage process consisting of Gap 1 (G1), synthesis (S), Gap 2 (G2) and mitosis (M), which a cell undergoes as it grows and divides. After completing the cycle, the cell either starts the process again from G1 or exits the cycle through G0.
What are the three major phases of the cell cycle?
Interphase
How to explain the four phases of a cell cycle?
Phases of Cell Cycle Mitosis. Let’s start this cell cycle with “birth.” During mitosis, the “parent” cell goes through a complex series of steps to ensure that each “daughter” cell will get the materials G 1 Phase. In G 1 phase, the newly formed daughter cell grows. S Phase. During S phase, the cell replicates its DNA. G 2 Phase. An Alternative Path: G 0 Phase.
How much time do cells spend in each phase of mitosis?
Usually, cells will take between 5 and 6 hours to complete S phase. G2 is shorter, lasting only 3 to 4 hours in most cells. In sum, then, interphase generally takes between 18 and 20 hours. Mitosis, during which the cell makes preparations for and completes cell division only takes about 2 hours.
What is the first stage of the cell cycle?
There are two major parts of the cell cycle: mitosis and interphase. Within these two parts are several other identifiable stages. During interphase, three stages occur — a first growth stage, a DNA synthesis stage and then another growth stage.
