Biology Benchmark 1 Review (24-25)

Front

What is the stage of mitosis where the sister chromatids separate?

Back

Anaphase

Front

What is uncontrolled cell division that usually leads to tumors and disease?

Back

Cancer

Front

In which phase of the cell cycle does DNA replication take place?

Back

S phase

Front

During which part of the cell cycle is DNA copied?

Back

S phase

Front

What is a tumor in the context of disruptions of the cell cycle?

Back

A mass of cells that grow uncontrollably

Front

What are the main phases of the cell cycle?

Back

Interphase (G1, S, G2) and M phase (mitosis and cytokinesis)

Front

What occurs during the G1 phase of the cell cycle?

Back

Cell growth and preparation for DNA synthesis.

Front

What is the role of checkpoints in the cell cycle?

Back

To ensure that the cell is ready to proceed to the next phase and to prevent errors.

Front

What is the significance of the S phase in the cell cycle?

Back

It is the phase where DNA is replicated, ensuring that each daughter cell receives an identical set of chromosomes.

Front

What can result from mutations in genes that regulate the cell cycle?

Back

Cancer, due to uncontrolled cell division.
