SCIENCE

• The cell division is composed of mitosis and meiosis
• Body cells - Somatic cells
• Mitosis is composed of prophase, metaphase, anaphase, telophase
• Mitotic cells or spindle fiber
• Prophase

  • The chromosomes start to condense
  • The nuclear membrane starts to break down
  • The mitotic spindle begins to form
  • The nucleolus dissapears
• Metephase

  • The mitotic spindle connects to each chromosome
  • Chromosomes align at the metaphase plate
• Anaphase

  • The mitotic spindle begin to contract and become shorter
  • The sister chromatids separates from each other and are pulled towards the opposite ends of the cell
• Telophase

  • Chromosomes begins to decondense
  • The mitotic spindle disappears
  • Nuclear membranes and nucleoli reappear
• The cell cycle is divided into two the inter phase and the mitotic phase
• The interphase is composed of gap 1 phase, synthesis phase, gap 2 phase
• Gap 1 phase

  • The cells grow
  • make new sets of organelles
• Synthesis phase

  • The cell replicates its DNA
• Gap 2 phase

  • The cell continues to grow
• DNA- deoxyribonucleic acid
