The Cell Cycle

Question 1

Interphase

Answer 1

• Cell spends 90% of it life here
• Gap 1
• Synthesis
• Gap 2

Question 2

Gap 1 (Interphase)

Answer 2

• 1st stage
• cell carries out normal functions
• Cells increase in size and organelles increase in number
• requires checkpoint

Question 3

Synthesis (Interphase)

Answer 3

• 2nd stage
• DNA replication inside nucleus
• at end, cell has 2 identical sets of DNA

Question 4

Gap 2 (Interphase)

Answer 4

• 3rd stage
• Normal functions and additional growth
• Requires critical checkpoint

Question 5

Mitosis

Answer 5

-4th stage
-Division of Nucleus
-Prophase
-Metaphase
-Anaphase
-Telophase

Question 6

Prophase (mitosis)

Answer 6

-chromosomes condense, and spindle fibers form
-Nuclear membrane begins to dissolve
-Spindle fibers form

Question 7

Metaphase (mitosis)

Answer 7

-spindle fibers attach to centromere
-chromosomes line up in the middle of the cell
-Metaphase plate

Question 8

Anaphase (mitosis)

Answer 8

-sister chromatids, separate to opposite sides of the cell (toward the centrioles)
-Spindle fibers shorten

Question 9

Telophase (mitosis)

Answer 9

-The nuclear membrane reforms
-chromosomes begins to uncoil
-spindle fibers dissolve

Question 10

Cytokinesis

Answer 10

-process that divided cell’s cytoplasm in half
-animal cells pinch ~> cleavage furrow
-plant cells ~> cell plate
-end result is 2 identical daughter cells
