PMAT and Mitosis

What happens in the S phase?

• DNA Replication

• Cell growth

• Nucleus divides

• Proteins are created

What happens in the G1 phase

• Replications of DNA

• Cell doubles in size and organelles are doubled

• Cells assembles special material

• Cytoplasm divides

Which parts of the cell cycle are collectively known as Interphase

• Mitosis and Cytokinesis

• G1 and G2

• G1, S, and G2

• G2, Mitosis and Cytokinesis

During cell division, what occurs to a mother cell?

• 
  A mother cell will duplicate itself and make another mother cell

• A mother cell will split itself and make two daughter cells that are genetically identical to the mother

• A mother cell will split itself and make two daughter cells that are not genetically identical to the mother

• A mother cell will split 4 times and create additional mother cells

What is one thing that must occur prior to cell division occurring?

• A) 

  The cell needs to split first

• B) 

  The cell needs to determine its function first

• The cell needs to create proteins first

• The cell needs to replicate its DNA first

What is the difference between mitosis and cytokinesis?

• A) 

  Mitosis is when the cytoplasm divides, and cytokinesis is when the nucleus divides

• B) 

  Mitosis is when the nucleus divides, and cytokinesis is when the cytoplasm divides

• C) 

  Mitosis is when the mother cell splits into 2 daughter cells, and cytokinesis is when the 2 daughter cells split into 4 more

• D) 

  Mitosis and cytokinesis are both the same thing

What reasons causes cells to divide instead of growing continuously?

• A) 

  Cells can continue to grow indefinitely so long as we give them enough energy

• B) 

  Cells divide because it puts less pressure on the ribosomes

• C) 

  Cells divide because it puts less pressure on the DNA, and so that things can more easily move in and out of the cell

• D) 

  Cells divide because it puts more pressure on the DNA, and so that things take longer to move in and out of the cell

• D) 

  46 from your mother and 23 from your father, for a total of 69

What happens in G2 phase?

• A) 

  DNA replication

• B) 

  Special structures are created for division

• C)
