GENERAL BIOLOGY 1

• S phase


  This is when DNA replication occurs
• G1 phase


  This is the first stage of the interphase
• G1 phase or G2 phase


  The growth of the cell happens in this phase
• mitosis


  This refers to the division that occurs in somatic cells
• meiosis


  This refers to the division that occurs to produce sex cells
• G2 checkpoint


  This checks if the chromosomes are properly duplicated
• cytokinesis


  This refers to the division of the cytoplasm
• cytokinesis


  This is when the cleavage furrow or cell plate appears
• S phase


  This is when the cell duplicates its genetic material
• G1 checkpoint


  This is the first interphase checkpoint
• mitosis: somatic cells

  meiosis: sex cells or gametes
• gap 1phase: G1-to-S checkpoint

  mitosis: metaphase checkpoint
• diploid: 46 chromosomes

  haploid: 23 chromosomes
• mitosis: nucleus

  cytokinesis: cytoplasm
• plants: cell plate

  animals: cleavage furrow
• interphase: chromatin

  mitosis: chromosomes
• condensed: chromosome

  uncoiled: chromatin
• animals and plants: life cycle

  cell: cell cycle
• chromosomes: homologous pairs

  chromatids: sister chromatids
• haploid: one set

  diploid: two sets
