The Cell Cycle and Mitosis Review (1st)

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 duplication (replication). It consists of interphase and the mitotic phase.

Front

What are the main phases of the cell cycle?

Back

The main phases of the cell cycle are Interphase (G1, S, G2) and the Mitotic phase (M phase, which includes mitosis and cytokinesis).

Front

What happens during interphase?

Back

During interphase, the cell grows, replicates its DNA, and prepares for mitosis. It consists of G1 (growth), S (DNA synthesis), and G2 (preparation for mitosis).

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells from a single parent cell.

Front

What is cytokinesis?

Back

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

Front

What occurs during prophase?

Back

During prophase, chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and spindle fibers begin to form.

Front

What happens during metaphase?

Back

During metaphase, chromosomes align at the cell's equatorial plane, and spindle fibers attach to the centromeres of the chromosomes.

Front

What is anaphase?

Back

Anaphase is the phase of mitosis where sister chromatids are pulled apart towards opposite poles of the cell by the spindle fibers.

Front

What occurs during telophase?

Back

During telophase, the chromosomes reach the poles, the nuclear envelope re-forms around each set of chromosomes, and the chromosomes begin to de-condense.

Front

What is the role of centrioles in mitosis?

Back

Centrioles help organize the spindle fibers that separate the chromosomes during mitosis.
