CELL CYCLE

• It is an ordered series of events involving cell growth and cell division that produces two new daughter cells.

  Cell Cycle
• What are the two major phase of Cell Cycle?

  1. Interphase
  2. Mitotic phase
• During this phase, the cell grows and DNA is replicated.

  Interphase
• During this phase, the replicated DNA and cytoplasmic contents are separated and the cell divides.

  Mitotic Phase
• What are the three stages of Interphase?

  1. G1 Phase
  2. S Phase
  3. G2 Phase
• This is the first stage of interphase, and is called the 'first gap.'

  G1 Phase
• During this stage of interphase, the centrosome is duplicated.

  S Phase
• The S Phase is also called as...

  Synthesis phase
• This stage of interphase involves cell growth and protein synthesis.

  G1 phase
• During interphase, this stage involves DNA replication and the replication of the centrosome.

  S Phase
• During interphase, this stage involves further cell growth and protein synthesis.

  G2 Phase
• This phase ends when mitosis begins.

  G2 phase
• During this stage of interphase, the cell grows more, makes proteins and organelles, and begins to reorganize its contents in preparation for mitosis.

  G2 phase
• G2 phase is also called...

  Second Gap Phase
• During this interphase, chromatin condenses into chromosomes; nuclear envelope breaks down; centrioles move apart and form spindle fibers; spindle attaches to kinetochores on sister chromatids at opposite poles of the cell.

  Prophase
• During this interphase, sister chromatids line up along the equatorial plane of the cell; spindle fibers attach to kinetochore regions of all chromosomes.

  Metaphase
• During this interphase, centromeres split, separating sister chromatids; sister chromatids are pulled toward opposite poles by shortening spindle fibers.

  Anaphase
• During this interphase, nuclear envelopes reform around separated sets of chromosomes; chromosomes begin to uncoil; spindle fibers break down.

  Telophase
• It is the second part of the mitotic phase during which cell division is completed by the physical separation of the cytoplasmic components into two daughter cells.
