Cell Cycle and Mitosis

What is Mitosis

• A process where cells grow in size

• A process of cell division, where cells multiply

Why must the DNA be replicated before the cell can divide by Mitosis

• So that the new cells can get an exact copy of the DNA

• so that the new cells can also divide its DNA

What must take place before the cell divide?

• The DNA must replicate

• The cell must rest

What are replicated chromosomes called

• Centromere

• sister Chromatids

• Centriole

What occurs in the G1 PHASE

• The cell organelles are destroyed

• The cell organelles replicate

• The cell divided in 2

In which phase the does the DNA replicate?

• G1 phase

• S phase

• G2 phase

In which phase do cells spend about 90% of their time?

• Mitosis -where they divide

• INTERPHASE

Which of the following represents the correct order of phases in the cell cycle?

• Prophase, Metaphase, Anaphase, Telophase,

  PMAT

• Metaphase, Prophase, Anaphase, Telophase,

  MPAT

What occurs in PROPHASE. Select all that apply. Select 3

• the nuclear envelop disappear

• The chromosome condenses

• The centrioles separate to opposite poles of the cell

• the DNA replicate

In Metaphase the chromosomes....

• Meet in the middle

• Separate to opposite ends
