Interphase

Front

What are the three phases of Interphase?

Back

G1 (Gap 1), S (Synthesis), and G2 (Gap 2)

Front

What occurs during the G1 phase of Interphase?

Back

The cell grows and carries out normal functions.

Front

What is the primary event that occurs during the S phase of Interphase?

Back

DNA replication.

Front

What is the purpose of the G2 phase in Interphase?

Back

The cell prepares for mitosis by assembling structures needed for cell division.

Front

What is the significance of DNA replication during the S phase?

Back

It ensures that each daughter cell receives an identical set of chromosomes.

Front

How does the G1 phase contribute to cell growth?

Back

The cell increases in size, synthesizes proteins, and produces organelles.

Front

What checkpoints exist in Interphase to ensure proper cell cycle progression?

Back

G1 checkpoint, G2 checkpoint, and M checkpoint.

Front

What role do cyclins play in the cell cycle?

Back

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

Front

What happens if a cell does not pass the G1 checkpoint?

Back

The cell may enter a resting state (G0 phase) or undergo apoptosis.

Front

What is the relationship between Interphase and mitosis?

Back

Interphase prepares the cell for mitosis by ensuring DNA is replicated and the cell is ready to divide.
