What is G2 phase? What is S phase? 4 stages of Mitosis: During this phase the nuclear membrane disappears

Management

  1. What is G2 phase?
  2. What is S phase?
  3. 4 stages of Mitosis:
  4. During this phase the nuclear membrane disappears.
  5. During this phase spindles are formed from protein fibers.
  6. During this phase 2 centrioles move to opposite ends of the cells; they form cilia-like hair called asters. The nucleus disappears as well.
  7. During this phase chromosomes are now visible and double.
  8. During this phase the double chromosomes arrange at the equator of the cell. They are attached by the centromere to the spindle fibers.
  9. During this phase the nuclear membrane has totally disappeared.
  10. During this phase the centromere splits and the joined chromatids separate and move to opposite poles of the cell.

  1. When the cell is about to divide, and produces organelles, proteins, and membranes

What is G2 phase?

  1. DNA synthesis. The cell is getting ready to divide, and copies chromosomes.

What is S phase?

  1. PMAT

4 stages of Mitosis:

  1. Prophase

During this phase the nuclear membrane disappears.

  1. Prophase

During this phase spindles are formed from protein fibers.

  1. Prophase

During this phase 2 centrioles move to opposite ends of the cells; they form cilia-like hair called asters. The nucleus disappears as well.

  1. Prophase

During this phase chromosomes are now visible and double.

  1. Metaphase

During this phase the double chromosomes arrange at the equator of the cell. They are attached by the centromere to the spindle fibers.

  1. Metaphase

During this phase the nuclear membrane has totally disappeared.

  1. Anaphase

During this phase the centromere splits and the joined chromatids separate and move to opposite poles of the cell.
