In the gel below which DNA fragment is the largest?
Hint: Pay attention to the direction of travel
A
B
C
D
In the gel below what process is used to separate fragments?
ultraviolet radiation
electricity
restriction enzymes
PCR
What is a polymerase chain reaction use for?
to make many copies of DNA
to separate DNA based on size
to cut DNA into fragments
to make restriction enzymes
What does DNA fingerprinting compare?
each gene making up a person's DNA
the proteins DNA codes for
repeating units in coding segments of DNA
repeating units in noncoding segments of DNA
What four things are needed in a PCR?
DNA to be copied, DNA polymerase, nucleotides, helicase
DNA to be copied, DNA polymerase, nucleotides, 2 primers
DNA to be copied, RNA polymerase, nucleotides, ligase
DNa to be copied, RNA polymerase, 2 primers, helicase
Why is heat used in a PCR?
to speed the process up
reattaches the DNA double helix
separates the original DNA strand so it can be copied
adds free floating nucleotides to the new DNA strand
How much DNA is made each PCR cycle?
doubles
quadruples
splits in half
maintains the same amount
How long are the DNA strands that result from being treated with restriction enzymes?
2-3 base pairs
4-8 base pairs
10-20 base pairs
unlimited base pairs
Which of the following is a potential adverse (negative) effect of genetic engineering?
Produce medicines
Save engaged species
Higher crop yield
Decreased genetic diversity
What is B?
Plasmid
Foreign gene
What is A?
Plasmid
Foreign gene
What molecular tool is needed to accomplish this process?
restriction enzymes
scissors
microarray
microscope analysis
Testing humans for a potential genetic disorder is an example of
gene knockout
transgenic studies
genetic screening
gene therapy
Name a way that genetic engineering in plants is beneficial
Decreased crop yield
Decreased resistance to disease
Increased resistance to disease
Increased pests
If I insert genes from a squid into your genome; you would be what kind of organism?
transgenic
recombinant
foreign
cisternic
This DNA fingerprint is of a child and his/her parents. Which fingerprint is the child?
Person 1
Person 2
Person 3
Unable to tell
The computer analysis of biological data is a main component of?
genomics
proteomics
DNA microarray
bioinformatics
Inserting a gene into a bacterial plasmid is an example of?
gel electrophoresis
gene therapy
recombinant DNA
genetic screening
Why can transgenic organisms express foreign genes?
This is false because they can't express foreign genes
Because organisms are based on the same genetic code
Because we can turn on/off certain genes
Because we can cut out the parts that don't match
