and the fact that DNA molecules are negatively charged?
Restriction enzymes are used to cut DNA at specific locations - CORRECT ANSWER Please choose the
statement that best describes the role of restriction enzymes in genetic engineering.
Southern blot analysis is used to identify DNA fragments that are carrying specific DNA sequences. -
CORRECT ANSWER Please choose the statement that best expresses the goal of Southern Blot analysis.
RNA polymerase
DNA polymerase
Gel electrophoresis
dNTP deoxynucleotide triphosphates (dATP, dTTP, dGTP,dCTP)
Primers
Fragment of DNA to be sequenced - CORRECT ANSWER Please select all of the necessary components
for sequencing DNA. Assume you have already purified the DNA that you wish to sequence.
Denaturation - CORRECT ANSWER Heating target DNA to 94 degrees Celsius to separate it into two
strands
, Priming - CORRECT ANSWER Cooling to approximately 60 degrees Celsius to allow the oligonucleotide
primers base-pair with specific sites
Extension - CORRECT ANSWER Raising the temperature to 72 degrees Celsius and adding DNA
polymerase and nucleotides
DNA (gene) to be cloned
ddNTPs
Cloning vector
Restriction endonucleases
RNA polymerase
Screening for recombinants
Bacterium serving as host (cloning host) - CORRECT ANSWER Please select all of the materials and
procedures necessary to clone a gene into a bacterium. Assume the gene to be cloned has been isolated
and purified
Antibiotics - CORRECT ANSWER Which of the following is NOT a type of protein product obtained
through recombinant DNA technology
true - CORRECT ANSWER T/F Biotechnologists have developed and tested bacteria that may be used to
clean up oil spills
false - CORRECT ANSWER T/F One benefit of transgenic animals is that they will not automatically
transcribe and translate eukaryotic genes and accurately carry out posttranslational modification of the
protein
