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