Card Set Information
What are the 2 limits to cell growth
surface area to volume ratio
What is cellular communication?
larger= more demand on DNA and harder to get info around
What increases faster volume or surface area?
How is a cell's DNA like books in a library>
The rate @ which materials enter and leave through the cell membrane depends on
What are the 2 new cells called after cell division occurs?
What is the point @ which the chromatids are attached?
Which phase consists of major cell growth?
G1 or interphase
List & describe 3 points of cell cycle
mitosis= division of nucleus
cytokinesis= division of cytoplasm
Which phase is DNA replicated?
what are the 3 stages of mitosis?
what 3 important things happen during prophase
chromatin condenses into chromosomes
spindle fibers form
What are spindle fibers made of
volume has to do with
size of cell
surface area has to do with
waste products out
what is chromatin
relaxed form of DNA (uncoiled)
what is a chromosome
carry genetic info
made of protein & DNA
what are sister chromatids
identical strands of DNA
prepared for mitosis
cell plate forms
pinched into 2
why do cells divide
to help you grow, to heal
what 2 cells form from sister chromatids
process that forms daughter cells
when do chromosomes become visible
what happens during metaphase
chromosomes line up @ equator
what happens during anaphase
divide and sister chromatids move to opposite poles
what happens during telophase
what is a cycline
protein binds to enzymes
starts G2 and S phase
regulates cell life
what is cancer
unregulated cell growth
2 types of stem cells
stem cells are
