Unit 3: Cell Cycle & Mitosis

Front

What is cytokinesis?

Back

Cytokinesis is the process during cell division where the cytoplasm divides into two new daughter cells.

Front

What is a centromere?

Back

A centromere is the structure that holds sister chromatids together during cell division.

Front

What are sister chromatids?

Back

Sister chromatids are two identical copies of a chromosome, joined together by a centromere.

Front

What is cancer in relation to the cell cycle?

Back

Cancer is the uncontrolled reproduction of cells due to mutations that disrupt the normal cell cycle.

Front

What occurs during telophase?

Back

During telophase, two new nuclei form around the separated sets of chromosomes.

Front

What is the role of spindle fibers in mitosis?

Back

Spindle fibers help separate the sister chromatids and pull them to opposite sides of the cell during mitosis.

Front

What happens during prophase?

Back

During prophase, chromatin condenses into visible chromosomes, and the nuclear envelope begins to break down.

Front

What is the significance of the cell cycle?

Back

The cell cycle is crucial for growth, development, and repair in multicellular organisms, ensuring proper cell division.

Front

What is apoptosis?

Back

Apoptosis is the process of programmed cell death that occurs in multicellular organisms.

Front

What are the phases of the cell cycle?

Back

The cell cycle consists of interphase (G1, S, G2) and the mitotic phase (mitosis and cytokinesis).
