Largest part of the cell cycle

Interphase

1

Three stages of interphase

1. G1
2. S
3. G2

2

Synthesis phage (S)

Phase where DNA is replicated

3

Gap 1 phase (G1)

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

4

Gap 2 phase (G2)

Continue cell growth getting ready for mitosis

5

Four steps of mitosis

Prophase
Metaphase
Anaphase
Telophase/cytokenesis

6

Heterochromatin vs euchromatin

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

7

Prophase

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

8

Metaphase

-chromosomes lined up at plate
-spindle fibers from centrioles have attached to the centromeres of each chromosome

9

Anaphase

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

10

Telophase

-nuclear membranes reformed
-cytokenesis occurs dividing into two cells
