Genetic Engineering II
Test Description: Practice
Instructions: Answer all questions to get your test result.
1) Genetic engineering involves
A
reinserting DNA into living organisms
B
all of the above
C
editing a DNA sequence
D
reading a DNA sequence
2) Analyzing DNA by gel electrophoresis allows researchers to
A
identify similarities and differences in the genomes of different kinds of organisms.
B
determine whether a particular allele of a gene is dominant or recessive.
C
compare the phenotypes of different organisms.
D
cut DNA with restriction enzymes
3) Knowing the sequence of an organism’s DNA allows researchers to
A
study specific genes.
B
cut the DNA
C
mutate the DNA
D
reproduce the organism
4) The process of making changes in the DNA code of living organisms is called
A
genetic engineering
B
selective breeding
C
inbreeding
D
hybridization
5) Ian Wilmut’s cloning of Dolly in 1997 was considered a breakthrough in genetic engineering because
A
scientists thought cloning was impossible
B
scientists thought only fetal cells could be used to produce clones.
C
scientists had never before isolated mammary cells
D
sheep had never responded well to gene technology procedures
6) A gene that codes for resistance to glyphosate has been added to the genome of certain plants. These plants will
A
convert glyphosate to fertilizer
B
die when exposed to glyphosate
C
survive when glyphosate is sprayed on the field
D
produce chemicals that kill weeds growing near them
7) DNA fingerprinting has been used in criminal investigations because
A
DNA analysis allows investigators to distinguish body cells of different individuals, who are unlikely to have the same DNA
B
bacterial DNA on the hands of criminals may provide a clue as to where that person was when the crime was committed
C
criminals leave DNA samples behind them when they touch an object at a crime scene
D
DNA found on murder weapons is easy to identify
8) The risk associated with vaccines prepared by injecting killed or weakened pathogenic microbes is that
A
the antibodies that result may not work
B
a few remaining live or unweakened microbes could still cause the disease
C
None of the above
D
the vaccine protects only against other diseases
9) The goal of the Human Genome Project is to
A
create maps showing where genes are located on human chromosomes
B
identify people with genetic diseases
C
treat patients with genetic diseases
D
create maps showing where chromosomes are located on human genes
10) The use of genetic engineering to transfer human genes into bacteria
A
is impossible with current technology
B
allows the bacteria to produce human proteins
C
causes the human genes to manufacture bacterial proteins
D
results in the formation of a new species of organism
