• Reasons for cellular reproduction/mitosis
• Growth: Allows organisms to grow by increasing cell numbers.
• Repair: Replaces damaged or dead cells.
• Reproduction: Enables asexual reproduction in some organisms and prepares gametes for sexual reproduction through meiosis.
• The Cell Cycle- knows what occurs in each step, with an emphasis on DNA.
• Interphase (Preparation for Division)
• G1: The cell grows, performs its routine functions, and prepares for DNA replication.
• S (DNA synthesis): DNA is replicated, doubling the genetic material. The cell is particularly vulnerable here.
• G2: Additional growth may occur, and the cell ensures all necessary chemicals are ready for division.
