plasmid ring
a bacteriophage can be an important part of the genetic engineering process. determine which of the following structures is not part of a bacteriophage.
transgenics
a research group is looking for a way to use spider silk, valued for its high tensile strength, to make extremely strong ropes, but spiders only produce small amounts of silk. They have isolated the gene and have inserted it into cows to produce the silk protein in their milk where the scientists can collect it in large quantities. what is this process called?
bacteriophage
a scientist is attempting to produce a large quantity of Insulin. in order to transfer the gene for Insulin production into the bacteria that will be making it, the scientist should use a(n) ___________.
putting the bacterium into a fermenter
a scientist successfully creates a bacterium with a recombinant plasmid for producing Insulin; however, one bacterium can only create a tiny amount of Insulin. what process should be used next?
II, I, IV, III
determine the correct sequence of events during the creation of recombinant DNA. I. Plasmid is cut open with enzymes II. Target gene is cut out with enzymes III. Plasmid is inserted into the bacterium IV. Target gene is bonded to the plasmid with Ligase
I, IV, II, III
determine the correct sequence of events for the production of a human protein in a bacterium. I. Target gene is inserted into a plasmid II. Bacterium replicates in a fermenter III. Bacteria produces target protein IV. Modified plasmid is inserted into bacterium
they bond to the recognition site
during genetic engineering, how do Restriction enzymes know what base pairs to act on?
to bond the target gene to the plasmid with covalent bonds .
during genetic engineering, what is the function of a Ligase enzyme?
changing the DNA of a living thing to change its characteristics
genetic engineering is best described as:
they can be given bacterial DNA to produce a toxin that only works on bugs and other pests
how can plant crops be modified so that they do not need to be sprayed with pesticides that are also harmful to humans like normal crops are?
Hepatitus B vaccine
if a scientist isolates genes for Hepatitus B antigens from a Hepatitus virus, then inserts them into a bacterial plasmid and replicates the bacteria in a fermenter, what product will be collected?
influenza evolves very quickly and its antigens mutate so that your memory cells from the last vaccine won't recognize it
if a vaccine protects you for most of your life against a particular pathogen, why do you need a new flu shot every year?
III, II, IV, I
put the main steps of genetic engineering in the correct order. I. Replicate the new organism II. Isolate the genes from the specialist cell III. Select the desired trait IV. Insert the genes into the target organism
two light and two heavy polypeptide chains

what is used to isolate and cut the target gene during genetic engineering?
all of these
what might an elevated ST segment of an ECG mean?

who developed the theory that diseases only have natural causes?
bacteria make proteins differently than mammals, and cannot make certain human proteins
why are genetically engineered mammalian cells sometimes needed to produce certain proteins instead of genetically engineered bacteria?
bacteria make proteins differently than mammals, and cannot make certain human proteins.
why are genetically engineered mammalian cells sometimes needed to produce certain proteins instead of genetically engineered bacteria?
the modified crops could make people very sick
