The Cell Cycle And Mitosis Worksheet Answer Key Pdf
The cell cycle is a series of events that lead to the division of one cell into two genetically identical daughter cells. The cell cycle has two main stages: Interphase and the M-phase (mitosis). These two stages are divided into multiple phases, each with a specific set of events that occur in the cell. Understanding the cell cycle and mitosis is important because it forms the basis of cell division and growth in all living organisms.
The Cell Cycle
The cell cycle can be divided into two major stages: Interphase and the M-phase (mitosis). Interphase is the stage in which the cell grows and carries out normal cellular functions. During this phase, the cell prepares for cell division by replicating its DNA and organelles. The M-phase, or mitosis, is the stage in which the cell divides into two daughter cells. Mitosis can be divided into four phases: Prophase, Metaphase, Anaphase, and Telophase.
Interphase
Interphase can be divided into three phases: G1, S, and G2. During G1, the cell grows and carries out normal cellular functions. During the S phase, the cell replicates its DNA. Finally, during the G2 phase, the cell prepares for mitosis by synthesizing proteins and organelles.
Mitosis
During mitosis, the cell divides into two genetically identical daughter cells. Mitosis can be divided into four phases: Prophase, Metaphase, Anaphase, and Telophase.
Prophase
During prophase, the chromatin in the cell condenses into visible chromosomes. The nuclear envelope also breaks down, and the spindle fibers begin to form at opposite ends of the cell.
Metaphase
During metaphase, the chromosomes line up at the equator of the cell. The spindle fibers attach to the centromeres of the chromosomes.
Anaphase
During anaphase, the spindle fibers pull the sister chromatids apart at the centromeres. The chromatids move towards opposite ends of the cell.
Telophase
During telophase, the chromosomes arrive at the opposite ends of the cell. The nuclear envelope reforms around each set of chromosomes, and the spindle fibers break down. The cell then prepares to divide into two daughter cells during cytokinesis.
