Cell Cycle and Mitosis

Front

What is the cell cycle?

Back

The cell cycle is a 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 the S phase of the cell cycle?

Back

DNA replication occurs during the S phase, where each chromosome is duplicated to form sister chromatids.

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 are sister chromatids?

Back

Sister chromatids are identical copies of a chromosome, connected by a centromere, formed during DNA replication.

Front

What is the role of spindle fibers in mitosis?

Back

Spindle fibers help separate sister chromatids during mitosis by attaching to the centromeres and pulling them apart.

Front

What is the centromere?

Back

The centromere is the region of a chromosome where sister chromatids are joined together, playing a crucial role during cell division.

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 is metaphase?

Back

Metaphase is the stage of mitosis where chromosomes align at the cell's equatorial plane, preparing for separation.

Front

What happens during anaphase?

Back

During anaphase, sister chromatids are pulled apart to opposite poles of the cell by the spindle fibers.

Front

What is telophase?

Back

Telophase is the final stage of mitosis where the chromosomes de-condense, the nuclear envelope re-forms, and the cell prepares to divide.
