Cell Cycle

Front

What is interphase?

Back

Interphase is the phase of the cell cycle where the cell spends most of its life, preparing for cell division. It consists of three stages: G1 (cell growth), S (DNA synthesis), and G2 (preparation for mitosis).

Front

What happens during the G1 phase of interphase?

Back

During the G1 phase, the cell grows and develops, synthesizing proteins and organelles necessary for DNA replication.

Front

What is the S phase of interphase?

Back

The S phase (Synthesis phase) is the part of interphase where DNA replication occurs, resulting in two identical sets of chromosomes.

Front

What occurs during the G2 phase of interphase?

Back

During the G2 phase, the cell continues to grow and prepares for mitosis by producing proteins and organelles needed for cell division.

Front

What is mitosis?

Back

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

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 happens during prophase of mitosis?

Back

During prophase, chromosomes condense and become visible, the nuclear envelope breaks down, and spindle fibers begin to form.

Front

What occurs during metaphase of mitosis?

Back

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

Front

What is anaphase in mitosis?

Back

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

Front

What happens during telophase of mitosis?

Back

During telophase, the chromosomes decondense, the nuclear envelope re-forms around each set of chromosomes, and the cell prepares to divide.
