Mitosis:  Meiosis: Each resulting cell still has chromosomes from mom & dad
Mitosis ,[object Object],[object Object],[object Object]
Vocabulary ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
Interphase  occurs just before Mitosis begins: DNA is replicated along with organelles and other cellular components and the cell prepares for division.  http://www.bioweb.uncc.edu/1110Lab/notes/notes1/lab6.htm
Mitosis  Interphase ,[object Object],[object Object],Photographs from: http://www.bioweb.uncc.edu/biol1110/Stages.htm
1 st  step in Mitosis:   Prophase (preparation phase) http://www.bioweb.uncc.edu/1110Lab/notes/notes1/lab6.htm The DNA recoils, and the chromosomes condense; the nuclear membrane disappears, and the mitotic spindles begin to form.

Meiosis  Interphase Meiosis is preceded by interphase. The chromosomes have not yet condensed.  http://morgan.rutgers.edu/MorganWebFrames/Level1/Page7/meiosis1.html
Meiosis  Interphase   The chromosomes have replicated, and the chromatin begins to condense.  http://morgan.rutgers.edu/MorganWebFrames/Level1/Page7/meiosis1.html
Meiosis  Prophase I The chromosomes are completely condensed. In meiosis (unlike mitosis), the homologous chromosomes pair with one another  http://morgan.rutgers.edu/MorganWebFrames/Level1/Page7/meiosis1.html

Mitosis and meiosis

  • 5. Mitosis: Meiosis: Each resulting cell still has chromosomes from mom & dad
  • 6.
  • 7.
  • 8. Interphase occurs just before Mitosis begins: DNA is replicated along with organelles and other cellular components and the cell prepares for division. http://www.bioweb.uncc.edu/1110Lab/notes/notes1/lab6.htm

  • 10. 1 st step in Mitosis: Prophase (preparation phase) http://www.bioweb.uncc.edu/1110Lab/notes/notes1/lab6.htm The DNA recoils, and the chromosomes condense; the nuclear membrane disappears, and the mitotic spindles begin to form.

  • 23. Meiosis Interphase Meiosis is preceded by interphase. The chromosomes have not yet condensed. http://morgan.rutgers.edu/MorganWebFrames/Level1/Page7/meiosis1.html
  • 24. Meiosis Interphase The chromosomes have replicated, and the chromatin begins to condense. http://morgan.rutgers.edu/MorganWebFrames/Level1/Page7/meiosis1.html
  • 25. Meiosis Prophase I The chromosomes are completely condensed. In meiosis (unlike mitosis), the homologous chromosomes pair with one another http://morgan.rutgers.edu/MorganWebFrames/Level1/Page7/meiosis1.html

Editor's Notes

  1. Explain the randomness in meiosis End of first class
  2. Beginning of second class
  3. A mnemonic to help remember the stages of mitosis. Now do the mitosis flip books End of second class
  4. Beginning of third class
