Unit 6: Cell Cycle Review

Front

What is the G1 phase of interphase?

Back

The G1 phase is the first stage of interphase where the cell grows and prepares for DNA replication.

Front

What occurs during the S phase of the cell cycle?

Back

During the S phase, DNA is duplicated, ensuring that each daughter cell will have an identical set of chromosomes.

Front

What is the G2 phase of interphase?

Back

The G2 phase is the second stage of interphase where the cell continues to grow and prepares for mitosis.

Front

What is the M phase in the cell cycle?

Back

The M phase is the stage of the cell cycle where mitosis occurs, leading to the division of the cell into two daughter cells.

Front

What happens if a cell does not pass a checkpoint in the cell cycle?

Back

If a cell does not pass a checkpoint, it may pause to fix the problem or undergo apoptosis (programmed cell death).

Front

What are HeLa cells?

Back

HeLa cells are the first immortal cell line derived from human cancer cells, used extensively in scientific research.

Front

What is the purpose of checkpoints in the cell cycle?

Back

Checkpoints are mechanisms that ensure the cell is ready to proceed to the next phase, preventing errors in cell division.

Front

What is apoptosis?

Back

Apoptosis is a process of programmed cell death that occurs in multicellular organisms.

Front

Why is DNA duplication important during the S phase?

Back

DNA duplication is crucial because it allows each daughter cell to be genetically identical to the parent cell.

Front

What is the significance of the G1 and G2 phases in the cell cycle?

Back

Both G1 and G2 phases are important for cell growth and preparation for DNA synthesis and mitosis, respectively.
