Test Description: Practice
Instructions: Answer all questions to get your test result.
1) Genetic engineering involves
A
reading a DNA sequence
B
all of the above
C
reinserting DNA into living organisms
D
editing a DNA sequence
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
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
selective breeding
B
inbreeding
C
hybridization
D
genetic engineering
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
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 found on murder weapons is easy to identify
B
criminals leave DNA samples behind them when they touch an object at a crime scene
C
bacterial DNA on the hands of criminals may provide a clue as to where that person was when the crime was committed
D
DNA analysis allows investigators to distinguish body cells of different individuals, who are unlikely to have the same DNA
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 genes are located on human chromosomes
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
results in the formation of a new species of organism
C
causes the human genes to manufacture bacterial proteins
D
allows the bacteria to produce human proteins
