Copy of 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 make ATP

What is the stringy uncoiled form of DNA called?

• Chromosomes

• Chromatin

• Chromatography

• Chromoplast

What do we call the 2 identical copies of a chromatin?

• sister chromatids  

  (You should label the doubled (K-shaped) chromosomes that you drew on your cell cycle notes with this term.

• Don't pick this one - you need to know they are called sister chromatids!

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 is the other really important thing that a cell does during interphase?

• carries on normal functions (activities) - what it does for the majority of the cells' life.

• Cell division

• Sorts its chromosomes

Which event does NOT happen during prophase?

• The nuclear membrane disintegrates

• Chromatin condenses to form chromosomes

• DNA is replicated

• Spindle apparatus forms
