Mitosis

What is the function of the nuclear membrane?

• It provides energy to the cell.

• It encloses the nucleus, protecting the genetic material and regulating the passage of substances in and out of the nucleus.

• It synthesizes proteins for the cell.

• It stores waste products of the cell.

What is mitosis?

• Mitosis is the process of cell division that results in two genetically identical daughter cells from a single parent cell.

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

• Mitosis is a type of cell division that produces four genetically different daughter cells.

• Mitosis is the process of cellular respiration that generates energy for the cell.

What happens in Metaphase?

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

• Chromosomes are replicated and begin to condense into visible structures.

• The nuclear envelope breaks down, and spindle fibers begin to form.

• Chromosomes are pulled apart to opposite poles of the cell.

What are centrioles?

• A cylindrical organelle near the nucleus in animal cells, occurring in pairs and involved in the development of spindle fibers in cell division.

• A type of protein that helps in the formation of the cell membrane.

• A structure found in plant cells that stores nutrients and waste products.

• A small organelle responsible for energy production in cells.

What is a chromosome?

• A structure made of RNA that contains genetic information.

• A structure made of DNA and protein that contains genetic information.

• A type of cell that carries nutrients in the body.

• A molecule that helps in the synthesis of proteins.

What are the main phases of mitosis?

• Prophase, metaphase, anaphase, and telophase

• Interphase, prophase, cytokinesis, and telophase

• Prophase, anaphase, telophase, and synthesis

• Metaphase, anaphase, telophase, and replication

What is Anaphase?

• A phase where sister chromatids are pulled apart to opposite poles of the cell.

• A phase where chromosomes align at the cell's equator.

• A phase where the nuclear envelope re-forms around the separated chromosomes.

• A phase where DNA is replicated before cell division.

What is the role of the centromere in cell division?

• It is the region where the two sister chromatids are held together and is the attachment site for spindle fibers during cell division.

• It is the part of the chromosome that contains the genetic information.

• It is responsible for the replication of DNA during the S phase of the cell cycle.

• It helps in the formation of the nuclear envelope during cell division.

What is Interphase?

• The phase of the cell cycle where the cell prepares for division by replicating its DNA and organelles.

• The stage of cell division where chromosomes are separated.

• The phase where the cell undergoes apoptosis.

• The period of time when the cell is inactive and not dividing.

What are the phases of the cell cycle?

• The division cycle of most eukaryotic cells is divided into four discrete phases: M, G₁, S, and G₂. M phase (mitosis) is usually followed by cytokinesis. S phase is the period during which DNA replication occurs. The cell grows throughout interphase, which includes G₁, S, and G₂

• M, G1, S, G3

• M, G2, S, G1

• M, G1, S, G4
