Cell Cycle, Mitosis, & Meiosis

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. It consists of interphase (G1, S, G2 phases) and the mitotic phase (M phase).

Front

What happens during the S phase of the cell cycle?

Back

During the S phase, DNA replication occurs, resulting in the duplication of the genetic material in preparation for cell division.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two identical daughter cells, each with the same number of chromosomes as the parent cell.

Front

What is meiosis?

Back

Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four genetically diverse daughter cells, each with half the number of chromosomes.

Front

What are the phases of mitosis?

Back

The phases of mitosis are prophase, metaphase, anaphase, and telophase.

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

Why is DNA replication important before cell division?

Back

DNA replication is crucial to ensure that each daughter cell receives an exact copy of the genetic information from the parent cell.

Front

What is interphase?

Back

Interphase is the phase of the cell cycle where the cell spends most of its time, preparing for division by growing and replicating its DNA.

Front

What occurs during prophase?

Back

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

Front

What is the significance of the G1 phase?

Back

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