Flashcards in lab 7- cell cycle(test 1) Deck (8):
1

G1 phase

cell will grow and synthesize materials needed for the s phase

2

S phase

replicates its DNA and centrioles

3

G2 phase

cell completes growth and production of enzymes

4

Prophase

chromosomes condense and become visible
nuclear envelope and nucleolus disperse
spindle apparatus forms

5

metaphase

chromosomes align along the metaphase plate of cell
fibers of aster extend from centrosome to plasma membrane

6

anaphase

sister chromatids separate to opposite poles of the cell
events begin which leads to cytokinesis

7

telophase

nuclear envelope begins to reappear around two daughter nuclei
chromosomes condense
spindle disappears

8

cytokinesis

division of the cytoplasm into two cells
