In mitosis, the spindle fibers from two poles attach to each chromosome but in meiosis I, the spindle fibers from only ONE pole attaches to the chromosome.

WHAT IS MITOSIS AND MEIOSIS?

  • Mitosis and meiosis are two kinds of cell divisions. Mitosis involves separation of a single parent cell to produce two genetically identical cells while meiosis involves the separation of a single parent cell to produce four genetically different daughter cells.

WHAT IS SPINDLE FIBER?

  • Spindle fibers are structures that emanate from centrosome organelles and responsible for the separation of chromosomes during karyokinesis (nuclear division).

  • During the two cellular divisions (mitosis and meiosis), spindle fibers attach to the centromeres of each chromosome in order to align and eventually divide them.

However, in mitosis, spindle fibers from two opposite poles attach to each chromosome but in meiosis I, the spindle fibers from only ONE pole attaches to the chromosome.
