Which of the following situations is not genetic engineering?

Using yeast to convert sugar into alcohol

A bacteriophage can be an important part of the genetic engineering process. Determine which of the following structures is not part of a bacteriophage.

plasmid ring

You are part of a research group that is attempting to improve on the beneficial genetic modification of golden rice, to further reduce global hunger issues. Which of the following difficulties will you likely encounter?

Allergic reactions to the rice from people who were previously unaffected.

Which of the following is an example of Genetic Engineering?

Altering the DNA of yeast to create vaccines.

Which of the following situations involves Transgenics?

Gene for human antibodies being introduced to goats.

Herceptin cancer fighting antibodies cannot be produced through genetic engineering of bacteria. What is used instead to accomplish this?

Genetically engineered mammalian cells

Put the main steps of genetic engineering in the correct order.I. Replicate the new organismII. Isolate the genes from the specialist cellIII. Select the desired traitIV. Insert the genes into the target organism

III, II, IV, I

You are part of a research group that is attempting to improve on the beneficial genetic modification of golden rice, to further reduce global hunger issues. Which of the following is NOT a benefit you would see?

Rice crops that can also be put in fermenters to produce useable proteins

You are part of a research group that is attempting to improve on the beneficial genetic modification of golden rice, to further reduce global hunger issues. Which of the following difficulties will you NOT encounter?

The modified crops could make people very sick.

During genetic engineering, how do Restriction enzymes know what base pairs to act on?

They bond to the Recognition site.

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?

They can be given bacterial DNA to produce a toxin that only works on bugs and other pests.

During genetic engineering, what is the function of a Ligase enzyme?

To bond the target gene to the plasmid with covalent bonds .

What is the purpose of inserting a target gene into bacteria?

To make them produce a specific protein or other product that can be used by humans.

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?

Transgenics

Which of the following is not a variable that Bioreactors control to produce large amounts of microbes?

Ultraviolet radiation levels

Which of the following best describes Recombinant DNA?

not (DNA that has been copied into an mRNA strand.

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

not (IV, I, II, III,

Why are genetically engineered mammalian cells sometimes needed to produce certain proteins instead of genetically engineered bacteria?

not (Mammal cells are larger and can produce greater volumes of protein.

Which of the following is NOT a reason bacteria are good for genetic engineering?

not (they replicate very quickly.

What process is similar in function to genetic engineering but different in the mechanism it uses?

Breeding for specific traits

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

I, IV, II, III

Which of the following is not a benefit of Genetic Engineering?

Enhancing the effectiveness of the new DNA by spreading it to other plants

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?

Hepatitus B vaccine

Which of the following is a way that new DNA can be introduced to bacteria?

It can be injected by a virus.
