Understand the cell cycle: The cell cycle is a series of events that cells go through to grow, replicate their DNA, and divide into two daughter cells. It is essential for maintaining the health and functionality of organisms.
Identify the phases of the cell cycle: The cell cycle consists of interphase (G1, S, and G2 phases) and the mitotic phase (M phase). During interphase, the cell grows and replicates its DNA, while the mitotic phase involves the division of the cell's nucleus and cytoplasm.
Recognize the importance of accurate DNA replication: During the S phase of interphase, the cell ensures that its DNA is copied accurately. This is crucial for maintaining genetic integrity and preventing mutations that could lead to diseases like cancer.
Understand the role of cell division: The mitotic phase ensures that the replicated DNA is evenly distributed to the two daughter cells. This process is vital for growth, development, and tissue repair in multicellular organisms.
Connect the cell cycle to organismal functions: The cell cycle enables organisms to grow by increasing the number of cells, repair damaged tissues by replacing old or injured cells, and maintain homeostasis by replacing cells that have reached the end of their lifespan.
