Final Review 5 - Cell Cycle

Front

What is the cell cycle?

Back

The cell cycle is the series of events that take place in a cell leading to its division and replication. It consists of interphase (G1, S, G2) and the mitotic phase (M).

Front

What happens during Interphase?

Back

Interphase is the phase of the cell cycle where the cell spends most of its time. It includes G1 (cell growth), S (DNA synthesis), and G2 (preparation for mitosis).

Front

What is M Phase?

Back

M Phase, or mitotic phase, is the part of the cell cycle where the cell divides. It includes mitosis (nuclear division) and cytokinesis (cytoplasmic division).

Front

What occurs during the S phase?

Back

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

Front

What is the role of mitosis?

Back

Mitosis is the process of nuclear division that ensures each daughter cell receives an identical set of chromosomes.

Front

What is cytokinesis?

Back

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

Front

What is the significance of the G1 phase?

Back

The G1 phase is crucial for cell growth and preparation for DNA replication. Cells increase in size and synthesize proteins necessary for DNA synthesis.

Front

What is the G2 phase?

Back

The G2 phase is the final stage of interphase where the cell prepares for mitosis by producing proteins and organelles needed for cell division.

Front

What is the purpose of cell division?

Back

Cell division is essential for growth, repair of damaged tissues, and replacement of dead or dying cells.

Front

What is anaphase?

Back

Anaphase is a stage in mitosis where sister chromatids are pulled apart to opposite poles of the cell.
