Cell Cycle and DNA Replication Test Review

Front

What is the result of DNA replication?

Back

DNA replication results in two DNA molecules, each with one new strand and one original strand.

Front

How many stages are in mitosis?

Back

There are 4 stages in mitosis.

Front

Why do cells go through the cell cycle?

Back

Cells go through the cell cycle for growth, repair, and reproduction.

Front

What units are repeatedly joined together to form a strand of DNA?

Back

Nucleotides are the units that are repeatedly joined together to form a strand of DNA.

Front

During which phase do the G1, S, and G2 phases occur?

Back

The G1, S, and G2 phases occur during Interphase.

Front

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

Back

The S phase is where DNA replication occurs, resulting in the duplication of chromosomes.

Front

What is cytokinesis?

Back

Cytokinesis is the process that divides the cytoplasm of a parental cell into two daughter cells.

Front

What are the main phases of the cell cycle?

Back

The main phases of the cell cycle are Interphase (G1, S, G2) and the M phase (Mitosis and Cytokinesis).

Front

What happens during the G1 phase of the cell cycle?

Back

During the G1 phase, the cell grows and synthesizes proteins necessary for DNA replication.

Front

What is the role of checkpoints in the cell cycle?

Back

Checkpoints in the cell cycle help ensure that the cell is ready to proceed to the next phase, preventing errors.
