Front

What is the result of mitosis?

Back

Mitosis results in 2 identical diploid cells.

Front

What stage of the cell cycle is known as the resting phase where the cell no longer divides?

Back

G0 phase.

Front

What are the three parts of a signal transduction pathway?

Back

Reception, transduction, response.

Front

What type of feedback mechanism amplifies responses in biological organisms?

Back

Positive Feedback.

Front

How do cyclin and CdK interact during the cell cycle?

Back

Cyclin interacts with CdK to initiate the mitotic phase.

Front

What is the primary purpose of mitosis?

Back

To produce two identical daughter cells for growth and repair.

Front

What is the difference between diploid and haploid cells?

Back

Diploid cells have two sets of chromosomes, while haploid cells have one set.

Front

What is the role of cyclins in the cell cycle?

Back

Cyclins regulate the timing of the cell cycle by activating cyclin-dependent kinases (CdKs).

Front

What happens during the G1 phase of the cell cycle?

Back

The cell grows and synthesizes proteins necessary for DNA replication.

Front

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

Back

The S phase is when DNA replication occurs, resulting in two copies of each chromosome.
