3.24c Mitosis 3



  • We look down the microscope we would be unable to absorb the chromosomes. During the interphase the DNA replication occurs.
  • The nucleus break down in the phase of the prophase the chromosomes become visible.
  • The nucleus is gone. Insides the cell a network of protein molecules known as a "Spindle"/ fibres. Extend from one pole of the cell to another, which is known as late prophase.
  • The metaphase is showing one pair of chromotids. The chromosomes are in the middle. The anaphase the fibre shortens, pulling each direction and the pair of chromotids moving apart to the poles and separate pair of chromotids later.
  • Telophase is when the nucleus began to form. We see two set of chromosomes in each end. Cytokinesis is when there are new copy of chromosomes.
