Mitosis and The Cell Cycle A

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 the Cell Cycle?

Back

The Cell Cycle is the series of phases that a cell goes through to grow and divide, including interphase and mitotic phase.

Front

What is the G1 phase?

Back

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

Front

What is the S phase?

Back

The S phase is the part of interphase where DNA is replicated, resulting in two copies of each chromosome.

Front

What is the G2 phase?

Back

The G2 phase is the second growth phase of interphase where the cell prepares for mitosis by producing proteins and organelles.

Front

What is the M phase?

Back

The M phase is the mitotic phase where the cell divides its copied DNA and cytoplasm to form two new cells.

Front

What are Chromosomes?

Back

Chromosomes are structures made of DNA and proteins that contain genetic information; they become visible during cell division.

Front

What is a Centromere?

Back

A centromere is the region of a chromosome where the two sister chromatids are joined and where the spindle fibers attach during mitosis.

Front

What is a Centriole?

Back

Centrioles are cylindrical structures that help organize the assembly of spindle fibers during cell division.

Front

What happens during Prophase?

Back

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