Cell Cycle 3/17+18

What is the main purpose of mitosis?

• To create haploid cells

• To replace old and dying cells with new diploid cells

• To reduce the number of chromosomes in cells

• To create specialized cells with unique functions

During which stage of the cell cycle do cells perform their specific functions?

• Prophase

• Metaphase

• Interphase

• Telophase

What happens during the S stage of interphase?

• The cell increases in size

• The nucleus dissolves

• DNA synthesis occurs

• Cytokinesis takes place

What structure forms during prophase to help move chromosomes?

• Spindle fibers

• Cell membrane

• Golgi bodies

• Lysosomes

What is chromatin?

• A type of cell membrane

• A protein structure in the nucleus

• Loose, uncoiled form of DNA

• A type of spindle fiber

What process occurs during telophase that helps physically separate the cells?

• Mitosis

• Cytokinesis

• Synthesis

• Replication

Why is cancer related to mitosis?

• Cancer prevents mitosis from occurring

• Cancer cells are unable to divide

• Cancer cells are stuck in continuous mitosis

• Cancer only affects cells in interphase
