BIO111 Ch. 9 Review Part 1

What is the cell cycle?

• A random set of stages in a prokaryotic cell's life

• An orderly set of stages from the first division of a eukaryotic cell to the time the resulting daughter cells divide

• The process of organelle destruction in a cell

• The replication of RNA in a cell

What happens just prior to the next division in the cell cycle?

• The cell shrinks

• The number of organelles decreases

• DNA is replicated, the cell grows larger, and the number of organelles doubles

• The cell stops functioning

What are the two major stages of the cell cycle?

• Interphase and Mitotic stage

• Prophase and Telophase

• Cytokinesis and DNA replication

• Organelle doubling and cell shrinking

What does the Mitotic stage include?

• DNA replication and organelle destruction

• Mitosis and cytokinesis

• Interphase and prophase

• Cell shrinking and organelle doubling

What is the main function of the G1 checkpoint in the cell cycle?

• To ensure DNA replication is complete

• To check for DNA damage and commit the cell to division if growth signals and nutrients are available

• To verify proper alignment of chromosomes during mitosis

• To ensure the cell has completed cytokinesis

What happens at the G2 checkpoint if DNA is damaged and cannot be repaired?

• The cell proceeds to mitosis

• The cell undergoes apoptosis

• The cell enters the G0 phase

• The cell skips the checkpoint and continues dividing

What is the role of the M checkpoint in the cell cycle?

• To ensure DNA replication is complete

• To check for proper alignment of chromosomes before mitosis continues

• To verify the presence of growth signals

• To ensure the cell has enough nutrients to divide
