Mitosis Flashcards
Main stages of cell cycle
Interphase,mitosis, cytokinesis
When is DNA replicated
S phase of interphase
What are the phases of interphase
G1, S, G2 phase
Major growth of the cell, when new organelles are made
G1
DNA is in the form of chromatin
pair of centrosomes
nucleolus is visible
nuclear envelope present
G2
Stages of mitosis
early prophase, late prophase,
metaphase, anaphase and telophase.
When nucleoli disappear
spindle fibers begin to form
centrosomes move away from each other
Chromosomes visible
Early prophase
Nuclear envelope disappears
spindle fibers start to attach to chromosomes
Late prophase
chromosomes line up at equator of cell
spindle fibers at opposite poles
Metaphase
Centromere split apart
separated sister chromatids now called single chromosomes
cell elongates
anaphase
When chromosomes reach poles
spindle fibers break down
nucleolus reforms
nuclear membrane reforms
cleavage
telophase
cytokinesis
cytoplasm divides in half
ends with 2 genetically identical daughter cells
