BIO 110 EXAM 2 QUESTIONS AND
CORRECT VERIFIED ANSWERS
GUARANTIED PASS
what does the G1 checkpoint assess
this checkpoint assesses cell growth to determine if
a cell will divide, delay division, or enter the resting
stage
what does the G2 checkpoint assess
this checkpoint assesses replication that occurred
during S
what does the M checkpoint assess
this checkpoint assess the progression of mitosis
before continuing metaphase
Do prokaryotes have a simple or complex cell
cycle
simple
what are the two stages of cell division in a
simple cell cycle
replication and binary fission
what happens in replication
,the DNA is copied
what happens in binary fission
the parent cell is split into two daughter cells
what is the shape of DNA in a prokaryotic
chromosome
a single circle
What are the two different mechanisms that
Eukaryotes go through to divide up DNA
Mitosis and Meiosis
What is mitosis
division mechanism that occurs in nonreproductive
cells
what type of cells does mitosis take place in
somatic cells (body cells)
what is meiosis
cell division mechanism that occurs in sex cells
what cells does meiosis happen in
germ cells (sex cells)
What are the stages of the eukaryotic cell cycle
interphase, mitosis, cytokinesis
, What are the phases of interphase
G1 phase, S phase, G2 phase
What happens in the G1 phase of interphase
primary growth phase of cell following division
what phase do most cells spend majority of their
lifespan in
G1 phase
What happens in the S phase of interphase?
DNA replication
What happens in the G2 phase of interphase
replication of mitochondria and synthesis of
microtubules, further preparation for cell division
what happens in the M phase of interphase
a microtubular apparatus binds to the chromosomes
and moves them apart
What happens in the C phase of interphase
the cytoplasm divides, creating two daughter cells
does the chromosome number vary among
organisms
yes
how do chromosomes exist in somatic cells
