Cell Cycle

Front

What is the cell cycle?

Back

The cell cycle is the series of phases that a cell goes through to grow and divide, including interphase (G1, S, G2) and mitotic phase (mitosis and cytokinesis).

Front

What happens during G1 phase?

Back

During G1 phase, the cell grows and develops, synthesizing proteins and organelles 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 interphase?

Back

Interphase is the phase of the cell cycle where the cell prepares for division, consisting of G1, S, and G2 phases.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells, consisting of prophase, metaphase, anaphase, and telophase.

Front

What happens during prophase of mitosis?

Back

During prophase, chromosomes condense and become visible, and the nuclear envelope begins to disappear.

Front

What occurs during metaphase of mitosis?

Back

During metaphase, chromosomes line up along the equator of the cell, and spindle fibers attach to their centromeres.

Front

What is the role of spindle fibers during mitosis?

Back

Spindle fibers help separate the chromosomes and pull them toward opposite poles of the cell during anaphase.

Front

What happens during anaphase of mitosis?

Back

During anaphase, sister chromatids are pulled apart and move toward opposite ends of the cell.

Front

What occurs during telophase of mitosis?

Back

During telophase, the chromosomes begin to decondense, and the nuclear envelope reforms around each set of chromosomes.
