mitosis and cell cycle

• cell cycle


  -growth

  -DNA replication + mitosis

  -division
• 1 ) growth

  -cell grows in size

  -increases the number of subcellar structures it contains, such as mitocondria and ribosomes
• 2 ) DNA replicated and mitosis

  -each cell made has a full set of DNA
• chromanones


  -called a "Pair", one from mother and one from father. Humans have 23 pairs of chromanones (46 total)
• preparing for division

  -DNA condenses into chromanones (collied up packets of DNA)

  -each chromanone gets duplicated, duplicate stays attached to the original

  -genetic material must divide to each side of the cell for division to take place
• 3 ) division

  -cell membrane and cytoplasm pull apart forming two daughter cells

  -each cell has same DNA "identical" to parent cell started off with

  -these two daughter cells ca then help growth, development and repair

  -these will start the cell cycle all over again
