Metaphase: Centrioles are now at opposite poles of the cell, with spindle fibers growing outward in astral array. This will ensure that the order and colors of the “chromosomes” are arbitrary. Do not give the students any instructions in The fibers are pulling on them until theyĪll line up in two rows in the center of the room. The centrioles which are on opposite sides of the room. They should pretend that they are attached to two spindle fibers which, in turn,are attached to

Movement of duplicated centrioles to opposite polesĭevelopment of spindle fiber, which lengthen and attach to theĬhromosomes at the kinetochore and to the opposite centriole Prophase: disintegration of nuclear membrane and nucleolusĬondensation of chromatin into distinct chromosomes, each consisting of Explain that they each represent one chromosome. Have the students stand up in the cleared area of the room and hand each studentĪn envelope. Interphase: all chromosomal material and organelles are replicated during S phase Pink and blue represent that the chromosome was inherited from the mother or father. The numbers represent the numbered chromosome and the Explain that each envelope contains a piece of paper that is pink orīlue with a number printed on it. Read only the written information, be careful The instructor narrates the steps of mitosis.
