Unit 4: Cell Cycle, Mitosis, DNA

Front

What is apoptosis?

Back

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

Front

What is the end result of Mitosis/cytokinesis?

Back

The end result of Mitosis and cytokinesis is the formation of two identical daughter cells.

Front

What happens during cytokinesis?

Back

During cytokinesis, the cytoplasm of a parental cell divides into two daughter cells.

Front

What occurs during anaphase?

Back

During anaphase, the chromosomes are pulled apart and move toward opposite poles of the cell.

Front

What is the longest phase of the cell cycle?

Back

The longest phase of the cell cycle is interphase.

Front

What are the main stages of the cell cycle?

Back

The main stages of the cell cycle are interphase (G1, S, G2) and the mitotic phase (M phase, which includes mitosis and cytokinesis).

Front

What is the role of DNA during the cell cycle?

Back

DNA replication occurs during the S phase of interphase, ensuring that each daughter cell receives an identical set of chromosomes.

Front

What is the significance of checkpoints in the cell cycle?

Back

Checkpoints in the cell cycle are critical control mechanisms that ensure the proper progression of the cell cycle and prevent errors such as DNA damage.

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 is the function of spindle fibers during mitosis?

Back

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