The Cell And Mitosis

Question 0

Three stages of interphase

Answer 0

1. G1
2. S
3. G2

Question 1

Largest part of the cell cycle

Answer 1

Interphase

Question 2

Synthesis phage (S)

Answer 2

Phase where DNA is replicated

Question 3

Gap 1 phase (G1)

Answer 3

• make all the proteins and nucleic acids necessary for DNA replication
• organelle production

Question 4

Gap 2 phase (G2)

Answer 4

Continue cell growth getting ready for mitosis

Question 5

Four steps of mitosis

Answer 5

Prophase
Metaphase
Anaphase
Telophase/cytokenesis

Question 6

Heterochromatin vs euchromatin

Answer 6

Het- very tightly wound around histones. Inaccessible to transcription so they are not being expressed

Eu- much more loosely packaged. Accessable to tracription so they are being expressed

Question 7

Prophase

Answer 7

• chromosomes condense
• nuclear envelope disappearing
• centrioles migrate to opposite poles of the cell

Question 8

Metaphase

Answer 8

• chromosomes lined up at plate

- spindle fibers from centrioles have attached to the centromeres of each chromosome

Question 9

Anaphase

Answer 9

• sister chromatids are pulled apart
• spindle fibers are shortening
• cleavage furrows are beginning to form as cell is getting ready to divide

Question 10

Telophase

Answer 10

• nuclear membranes reformed

- cytokenesis occurs dividing into two cells
