Cell division

• What molecule carries genetic information in chromosomes?


  DNA
• What type of cell division ensures identical genetic information in new cells?

  Mitosis
• What is produced during mitosis?

  Daughter cells
• Why is it essential for new cells to contain identical genetic information?


  To maintain the organism's genetic consistency
• What are the stages of the cell cycle?


  • Cell growth
  • DNA synthesis
  • Mitosis
• What does the term 'synthesis' refer to in the cell cycle?


  Made or put together
• What is DNA?


  Deoxyribonucleic acid, carrying genetic information
• How does DNA replicate in chromosomes?

  Each strand produces an exact copy
• What are daughter cells?

  New cells produced from cell division
• How can the length of different stages of the cell cycle be estimated?

  Using a specific formula
• What is the formula to estimate the length of time in a phase of the cell cycle?

  Length of time in phase = \(\frac {observed~number~of~cells~at~that~stage}{total~number~of~cells~observed} \times total~length~of~time~of~cell~cycle\)
• What is the purpose of the video featuring Dr. Alex Lathbridge?

  To explain key facts about cell division
• What is the total length of time of the cell cycle used for?

  To calculate time in each phase
• What happens when an organism grows or becomes damaged?

  It needs to produce new cells
• How does mitosis differ from other types of cell division?

  Mitosis produces identical daughter cells
