Cell Division/Mitosis

Front

What is interphase?

Back

Interphase is the phase of the cell cycle where the cell prepares for division. It includes cell growth, DNA replication, and normal cellular functions.

Front

What occurs during the G1 phase of interphase?

Back

During the G1 phase, the cell grows in size, produces RNA, and synthesizes proteins necessary for DNA replication.

Front

What occurs during the S phase of interphase?

Back

During the S phase, DNA is replicated, 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.

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 are the main phases of mitosis?

Back

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

Front

What happens during prophase?

Back

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

Front

What happens during metaphase?

Back

During metaphase, chromosomes align at the cell's equatorial plane, and spindle fibers attach to the centromeres of the chromosomes.

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 happens during telophase?

Back

During telophase, the chromosomes reach the poles, the nuclear envelope re-forms around each set of chromosomes, and the chromosomes begin to de-condense.
