Cell Cycle Regulation

Front

What is the cell cycle?

Back

The cell cycle is a series of phases that a cell goes through to grow and divide, including interphase (G1, S, G2) and mitotic phase (M).

Front

What are the main phases of the cell cycle?

Back

The main phases are Interphase (G1, S, G2) and Mitotic Phase (M).

Front

What happens during the S phase of the cell cycle?

Back

During the S phase, DNA is replicated, resulting in two identical sets of chromosomes.

Front

What is the role of checkpoints in the cell cycle?

Back

Checkpoints are regulatory mechanisms that ensure the proper progression of the cell cycle and prevent errors such as DNA damage.

Front

What are cyclins?

Back

Cyclins are proteins that regulate the cell cycle by activating cyclin-dependent kinases (CDKs).

Front

What are cyclin-dependent kinases (CDKs)?

Back

CDKs are enzymes that, when activated by cyclins, drive the cell cycle forward by phosphorylating target proteins.

Front

What is apoptosis?

Back

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

Front

What is a carcinogen?

Back

A carcinogen is a substance that is known to cause cancer by inducing changes in cellular DNA.

Front

What is the consequence of eliminating the S phase from the cell cycle?

Back

If the S phase is eliminated, daughter cells would have half the genetic material of the parental cell.

Front

What is the G0 phase?

Back

The G0 phase is a resting state where cells are not actively preparing to divide and may exit the cell cycle.
