spindle
-
what anchors the spindle?
centrioles
-
what are the four phases of mitosis?
- prophase
- metaphase
- anaphase
- telophase
-
how many daughter cells are created from mitosis and cytokinesis?
2
-
during what phase does cytokinesis begin?
telophase
-
if a human cell has 46 chromosomes, how many chromosomes will be in each daughter cell?
46
-
if a dog cell has 72 chromosomes, hwo many daughter cells will be created during a single cell cycle?
2
-
each daughter cell (from a dog cell) has how many chromosomes?
72
-
nuclear membrane dissolves during what phase?
prophase
-
what structure holds the individual chromatids together?
centromere
-
what is division of the cell nucleus called?
mitosis
-
what is the division of the cytoplasm called?
cytokinesis
-
"in-between" period of growth in cell cycle
interphase
-
series of events that cells go through as they grow and divide
cell cycle
-
during which phase do mitosis and cytokinesis take place?
M phase
-
during which phase does chromosome replication, or synthesis, take place?
S phase
-
period of activity in which cells do most of their growing
G1
-
cells increase in size and synthesize new proteins and organelles during which phase?
G1
-
many of the organelles and molecules required for cell division are produced during which phase?
G2
-
first and longest phase of mitosis, during which chromosomes become visible
prophase
-
second phase of mitosis, during which chromosomes line up across the center of the cell
metaphase
-
third phase of mitosis, during which the centromeres that join the sister chromatids split, allowing the sister chromatids to separate and become individual chromosomes
anaphase
-
fourth and final phase of mitosis, during which the chromosomes begin to disperse into a tangle of dense material
telophase
