Read the following abstract and answer if you use Colchicine in actively dividing human cells, which stage
of mitosis, will they be arrested.
THE MECHANISM OF COLCHICINE INHIBITION OF MITOSIS I. Kinetics of Inhibition and the Binding of H~-
Colchicine EDWIN W. TAYLOR, Ph.D. 1965. From the Committee on Biophysics, The University of Chicago
ABSTRACT Ha-colchicine of high specific activity (2.5 curies per mM) was prepared in order to study the
mechanism of colchicine inhibition of mitosis in cultures of human cells, strain K.B. No direct effects on
the duration of the cell cycle or macromolecular synthesis were demonstrable at a concentration of
colchicine which completely inhibited mitosis. The radioactive compound was bound to the cells at a rate
proportional to colchicine concentration. The binding appeared to be reversible since the radioactivity of
the cells reached a maximum value for a given concentration and was correct answersC
The initiation of the S phase and the M phase of the cell cycle depends on _______ and _______ to
make _______.
A)
actin; myosin; fibers.
B)
Cdk; cyclin; MPF.
C)
ligand; enzyme; complex.
D)
insulin; receptor; G-protein.
E)
ADP; Pi; ATP. correct answersB
What are the main purposes of meiosis in sexual reproduction? correct answerscreate unique cells and
to create variation and gametes and reduce the number of chromosomes.
, The homologous chromosomes separate during ____________________ and their sister chromatids
separate during _____________ phase of meiosis.
A)
Anaphase I and Telophase I
B)
Prophase I and Anaphase II
C)
Metaphase I and Metaphase II
D)
Anaphase I and Anaphase II
E)
Telophase I and Telophase II correct answersD - simple recall. Make sure you know the events of each
stage in meiosis.
How does the chromosome number of each daughter cell is reduced to half the original amount during
meiosis?
A)
Chromosomes do not replicate during the interphase I preceding prophase I.
B)
Chromosomes replicate only once before meiosis I but the cell divides twice.
C)
Half of the chromosomes from each gamete are lost during fertilization.
D)
Sister chromatids separate during anaphase I but not in anaphase II of meiosis.
E)
Chromosome numbers are reduced to half during crossing over in prophase I. correct answersB -
Understand that the final 4 resulting daughter cells are haploid (one set of chromosomes). Single DNA
replication occurs before entering prophase I - no more DNA replication.
When do the cells undergoing meiosis become immediately haploid from a diploid parental cell?
