mitosis stages

• what is the order of mitosis

  prophase, metaphase, anaphase, telophase
• what is the first stage of mitosis

  prophase
• what happens in prophase


  the chromatin condenses into visible sister chromatids joined at the centromere
• what happens in prophase after the chromatids are joined at the centromere


  the centrioles move to opposite poles
• what happens in prophase when the centrioles have moved to opposite poles


  protein micro tubules form from each centriole and spindle develops
• what happens in prophase when the spindle develops from the micro tubles from each centriole


  the nuclear envelope disintegrates and the nucleolus disappears and the chromosomes move towards the equator of the cell
• what is the longest stage of mitosis


  prophase
• where is the spindle fibres located


  at the centromeres
• What happens in metaphase?


  Chromosomes line up along the equator of the
• where do chromosomes attach themselves along the equator


  to spindle fibres at the centromere
• what are spindle proteins


  these ate used to attach the centirole of the chromosome tot he centromere of the cell
• what phase comes after prophase


  metaphase
• what phase comes after metaphase


  anaphase
• what phase comes after anaphase


  telophase
• what is the fastest stage of mitosis


  anaphase
• what is the first stage of anaphase


  the spindle fibres contract and shorten causing the centromere top split and the sister chromatids to be pulled apart
• what happens to the sister chromatids that are pulled apart during anaphase


  the chromatids are pulled towards opposite poles with the centromere leading
• what happens tot eh chromosomes during telophase


  the chromosomes uncoil and lengthen
• what happens to chromosomes when they uncoil and lengthen


  they revert back to chromatids
• what happens to the spindle fibres during telophase


  they break down
• what happens to the nucleoli and nuclear membranes in telophase


  they reform
• what happens in cytokineses


  cytoplasm divides
• when a plant cell undergoes mitosis what forms along the equator


  a cell plate
• what does the cell plate form


  a new cellulose cell wall
• what is the shape of a animal cell before mitosis


  it is more rounded
• Do plant cells have centrioles?


  no
• where does mitosis occur most in animal cells`


  epithelia and bone marrow
• where deos mitosis occut in most plant cells


  in meristems
• what happens to the spindles in animal cells during mitosis


  it degenerates at telophase
• what happens to the spindles in plant cells during mitosis


  they are retained during the new cell wall formation
