Cell Growth and Division Flashcard

Front

What is the G1 phase of the cell cycle?

Back

The G1 phase is the first phase of the cell cycle where the cell grows and synthesizes proteins necessary for DNA replication.

Front

What occurs 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 G2 phase of the cell cycle?

Back

The G2 phase is the second growth phase where the cell continues to grow and prepares for mitosis.

Front

What happens during metaphase of mitosis?

Back

During metaphase, chromosomes align at the cell's equator, preparing for separation.

Front

What is the role of the mitotic spindle?

Back

The mitotic spindle is responsible for aligning chromosomes at the cell's equator and separating them during cell division.

Front

What is the function of the G1 checkpoint?

Back

The G1 checkpoint checks for cell size and DNA damage before the cell proceeds to DNA synthesis.

Front

What is cytokinesis?

Back

Cytokinesis is the process where the cytoplasm of a parental cell divides into two daughter cells after mitosis.

Front

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

Back

The S phase is crucial for ensuring that each daughter cell receives an identical set of chromosomes.

Front

What occurs during prophase of mitosis?

Back

During prophase, chromatin condenses into visible chromosomes, and the nuclear envelope begins to break down.

Front

What happens during anaphase of mitosis?

Back

During anaphase, sister chromatids are pulled apart to opposite poles of the cell.
