Mitosis

What happens during prophase?

• DNA condenses into chromosomes, centrioles and spindle fibers appear.

• Chromosomes align at the cell equator.

• Nuclear envelope breaks down and spindle fibers attach to chromosomes.

• Cytoplasm divides into two daughter cells.

What structure helps in the movement of chromosomes during mitosis?

• Centrioles

• Spindle fibers

• Chromatin

• Nuclear envelope

What is the first stage of mitosis?

• Metaphase

• Anaphase

• Prophase

• Telophase

What is the significance of DNA condensing into chromosomes?

• It allows for easier separation of genetic material during cell division.

• It increases the length of DNA strands.

• It prevents mutations in the genetic code.

• It enhances the replication speed of DNA.

What is the result of mitosis?

• Two identical daughter cells.

• Four genetically different daughter cells.

• One diploid cell and one haploid cell.

• Two cells with different genetic material.

What phase follows metaphase in mitosis?

• Anaphase

• Telophase

• Prophase

• Cytokinesis

What is the purpose of mitosis?

• To ensure that each daughter cell receives an identical set of chromosomes.

• To allow for genetic variation in offspring.

• To facilitate the exchange of genetic material between cells.

• To produce energy for cellular functions.

What occurs during metaphase?

• DNA lines up in the middle of the cell and DNA attaches to spindle fibers.

• Chromosomes are replicated and begin to condense.

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

• Sister chromatids are pulled apart to opposite sides of the cell.

What is the role of centrioles during mitosis?

• They help organize the spindle fibers.

• They replicate the DNA.

• They form the nuclear envelope.

• They assist in cytokinesis.

What happens during telophase?

• 2 new nuclei form.

• Chromosomes condense into chromatin.

• Spindle fibers disappear.

• Cytokinesis begins.
