Unit: Cell Cycle/Cancer/Stem Cells

What occurs during the S phase of the cell cycle?

• DNA is replicated, resulting in two copies of each chromosome.

• Cell growth and preparation for mitosis.

• Chromosomes are separated into two daughter cells.

• The cell undergoes apoptosis.

How does cytokinesis differ in plant and animal cells?

• In plant cells, cytokinesis involves the formation of a cell wall, while in animal cells, it involves the formation of a cleavage furrow.

• In plant cells, cytokinesis involves the formation of a cell plate, while in animal cells, it involves the formation of a cleavage furrow.

• In both plant and animal cells, cytokinesis involves the formation of a cell plate.

• In animal cells, cytokinesis involves the formation of a cell plate, while in plant cells, it involves the formation of a cleavage furrow.

What is a cleavage furrow?

• A type of cell division in plants

• An indentation that forms in an animal cell during cytokinesis

• A structure that helps in the formation of the cell wall

• A process of DNA replication

What occurs during the G2 phase of the cell cycle?

• The cell undergoes DNA replication.

• The cell continues to grow and prepares for mitosis.

• The cell divides into two daughter cells.

• The cell enters a resting state.

During which phase of the cell cycle is DNA replicated?

• G1 phase

• S phase

• G2 phase

• M phase

What are stem cells?

• Stem cells are fully differentiated cells that perform specific functions.

• Stem cells are undifferentiated cells that have the potential to develop into different cell types.

• Stem cells are cells that only exist in embryos and cannot be found in adults.

• Stem cells are specialized cells that cannot change into other types of cells.

What does it mean for stem cells to be undifferentiated?

• They have a specific job and function in the body.

• They do not have a specific job yet and can become various types of cells.

• They are only found in embryos and cannot be found in adults.

• They are fully developed cells that perform specialized functions.

What are the main phases of the cell cycle?

• Interphase (G1, S, G2) and the Mitotic phase (M phase)

• Prophase, Metaphase, Anaphase, and Telophase

• G1 phase, G2 phase, and Cytokinesis

• Interphase, Mitosis, and Meiosis

What occurs during the G1 phase of the cell cycle?

• The cell divides into two daughter cells.

• The cell grows and synthesizes proteins necessary for DNA replication.

• The cell undergoes DNA replication.

• The cell enters a resting state before division.

What is cytokinesis?

• Cytokinesis is the process during cell division where the cytoplasm of a parental cell is divided into two daughter cells.

• Cytokinesis is the phase of cell division where the nucleus divides into two nuclei.

• Cytokinesis is the process of DNA replication before cell division occurs.

• Cytokinesis is the stage of cell division where chromosomes align at the cell's equator.
