Mitosis/Cell Cycle

Front

What are the three main phases of interphase?

Back

G1 (Gap 1), S (Synthesis), G2 (Gap 2)

Front

What is the purpose of the S phase in the cell cycle?

Back

DNA replication occurs, resulting in two identical sets of chromosomes.

Front

What happens during prophase?

Back

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

Front

What is cytokinesis?

Back

The process where the cytoplasm of a parental cell divides into two daughter cells after mitosis.

Front

What is the role of spindle fibers during mitosis?

Back

Spindle fibers help separate the chromosomes and pull them to opposite poles of the cell.

Front

Define anaphase.

Back

The phase of mitosis where sister chromatids are pulled apart to opposite sides of the cell.

Front

What occurs during telophase?

Back

Chromosomes de-condense back into chromatin, nuclear envelopes reform around each set of chromosomes.

Front

What is the significance of the G1 phase?

Back

The cell grows and prepares for DNA replication, checking for any damage to DNA.

Front

What is the difference between mitosis and meiosis?

Back

Mitosis results in two identical daughter cells, while meiosis results in four genetically diverse gametes.

Front

What are chromatids?

Back

Identical halves of a duplicated chromosome, joined together at the centromere.
