histones: nucleosomes : : grapes:
grape jelly
peanut butter
grape vine

nucleosomes bunch up as the chromatin coils and appears as
beads on a string
chairs around a table
planes at a terminal
rays around a sun
centromeres: telomeres :: 50 yard line:

goalposts
players
centrioles
is the plural of centrosomes
attach sister chromatids
make the spindle fiber
appear at the end of cytokinesis
cytokinesis in plants varies from animals in that
plants make a cleavage furrow
plants make a cell plate
plants have less cytoplasm
usually the nuclear membrane doesnt fully form as fast as that of the animal cell's nuclear membrane
when does the nuclear membrane disappear?
G2
Prophase
Cytokinesis
S phase
The spindle first starts to form in
prophase
metaphase
anaphase
telophase
What is not visible until the beginning of prophase
the nuclear membrane
centrioles
centromeres
chromosomes
when do chromosomes line up along the middle of the cell?
prophase
metaphase
anaphase
telophase
what is cell replication in a prokaryote called?
meiosis
reduction division
direct bacterial self cloning initiative (DBSCI)
binary fission
what is the order of the cell cycle
G1, S, G2, interphase, M phase, cytokinesis, mitosis
G1, G2, S, mitosis, cytokinesis
G1, S, G2, mitosis, cytokinesis
S, G1, G2, mitosis, cytokinesis
If I wanted to see DNA replication, which part of the cell cycle would I want to observe?
S phase
G1
G2
cytokinesis
what type of cell is most likely arrested (stopped) in G1 (pick all that apply)
nerve cells
cardiac muscle cells
skin cells
stomach cells

cytokinesis
what is the restriction point
the place where an animal cell pinches in half in cytokinesis
the point where sister chromatids are attached
the point where chromosomes attach to spindle fibers
the point in the cell cycle where the cell needs a hormone message in order to move to S phase
cells usually do not continue to divide when they become crowded. What is this called
platlet derived growth factors
density-independence
density-dependent inhibition
anchorage dependence
proteins that drive a cell cycle are: (chose all that apply)
cyclin-dependent kinases
cdks
cyclin
kinases
pdgf (chose all that apply)
are produced a locations of tissue damage
cause cells to move past the restriction point
stand for platelet derived growth factors
help repair wounds
cells that cause malignancy
do not respond to anchorage dependency
respond to density-dependent inhibition
lack kinases
can't make spindle fibers
cells derived from a cancer patient in 1951 and continue to divide today are called
transformational
HeLa cells
useless for anything other than cancer research
oogeneic templates
