Mitosis and the Cell Cycle - Bioman

What is the end product of cell division?

• one identical daughter cell

• two identical daughter cells

• 4 daughter cells that are genetically different

• 2 daughter cells that are genetically different

Which statement is NOT a reason we need the cell cycle?

• Replace worn out cells

• Heal tissue damage

• Growth

• To get smarter

What is the stringy uncoiled form of DNA called?

• Chromosomes

• Chromatin

• Chromatography

• Chromoplast

Why do cells need to copy their DNA before cell division?

• So there can be lots of mutations

• So that each daughter cell will be genetically identical to the parent cell

• Because chromosomes look better with two sister chromatids

• So the daughter cells have about half the genetic material of the parent cell

What are the 4 phases of Mitosis?

• Interphase, Mitosis, Cytokinesis

• Interphase, Prophase, Metaphase, Anaphase

• Prophase, Metaphase, Anaphase, Telophase

Which 3 events happen during Prophase?

• Chromosomes condense into chromatin,  nuclear envelope appears, and spindle fibers form

• Chromatin condenses into chromosomes, nuclear envelope disappears, and spindle fibers form

• Chromosomes line up in the middle of the cell and spindle fibers form

Which event does NOT happen during prophase?

• The nuclear membrane disintegrates

• Chromatin condenses to form chromosomes

• DNA is replicated

• Spindle apparatus forms

What happens during anaphase?

• chromosomes line up in the middle

• sister chromatids are walked APART

• DNA is replicated

How does the appearance of DNA change during telophase?

• chromosomes decondense back into chromatin

• chromatin condenses into chromosomes

• DNA disappears 

_________ is when the cell and its cytoplasm splits and 2 new daughter cells are formed.

• nucleus

• Telophase

• Cytokinesis
