BIL 150 Mallery: Test 4 || ALREADY PASSED.
a new drug, Serostat, blocks the formation of MPF (mitotic promoting factor) in cultured
HeLa cells. which of the following aspects of the reproduction of cells would most likely be
disrupted by Serostat? correct answers phosphorylation of proteins initiating mitosis
a particular cell has twice the amount of DNA as that in the diploid amount for this species.
This particular cell is most likely? correct answers in G2 interphase
the decrease in the amount of MPF activity at the end of mitosis is due to? correct answers
the degradation of cyclin
which of the following statements is most accurate concerning the protein cyclin? correct
answers it binds with a CDK (cyclin dependent kinase) forming active MPF (mitotic
promoting factor)
what stage of mitosis is depicted by the figure "C"? correct answers metaphase
meiosis II is similar to mitosis in that? correct answers sister chromatids separate
when homologous chromosome pairs during meiosis and allow crossover, which of the
following is likely to occur? correct answers two non-sister chromatids exchange chromatid
pieces
independent assortment of chromosomes results in the progeny all having an identical
combination of genetic traits in each of the progeny cells. correct answers false
sexual cell reproduction may be advantageous evolutionarily because? correct answers it can
provide genetic variability in heterogenous environments
Phenylketonuria (PKU) is a recessive human disorder in which an individual cannot
appropriately metabolize the essential amino acid PHE (phenylalanine). Thus an efficient and
effective treatment for PKU turns out to be which of the following? correct answers
regulating the diet of the affected persons to severely limit the uptake of PHE
an obstetrician knows that one of her patients is a pregnant woman, whose fetus is at risk for
a serious genetic disorder that is detectable biochemically in fetal cells. The obstetrician
would most reasonably offer which of the following procedures to her patient? correct
answers amniocentesis
many genes have more than just two differing alleles. Which of the following statements is
true of alleles? correct answers an individual will contain only two of all the possible alleles
for a gene
in corn plants, tall is dominant to short. If a heterozygous corn plant is crossed with a
homozygous tall plant, what is the probability that the offspring will be short? correct
answers 0%
