Exam 15: The Future Isnt What It Used to Be: Biotechnology

Dolly, the cloned sheep, is the product of which technique?

What is the function of restriction enzymes in bacteria?

Which of the following need to be included in a PCR reaction?

What is the purpose of introducing recombinant DNA plasmids into bacterial cells?

Tobacco plants have had a gene from fireflies inserted into them which makes them glow. These tobacco plants would be considered:

Biotechnology can be defined as the:

In reproductive cloning, a sperm is not used, but an egg is still required. Why?

In muscular dystrophy, muscle cells lack a protein called dystrophin, which leads to weakening of the muscles. As a biomedical researcher, your goal is to create a gene therapy approach to treating muscular dystrophy. You have a sequence of DNA that contains the dystrophin gene and a virus that infects human cells. You want to combine the dystrophin gene with the viral DNA so that the virus can infect and insert the gene into the muscle cells as a way to treat the disease. Explain how you would get the dystrophin gene into the viral DNA.

________ involves the fusion of a somatic cell with an enucleated egg cell.

Which statement is a characteristic of plasmids?

In PCR, heating of the DNA is necessary because:

To identify an individual through DNA analysis of his or her blood at crime scenes, investigators look for patterns based on:

How similar to the donor would a cloned human be?

In producing Dolly, the first cloned sheep, how many different sheep were involved, either contributing cells or acting as a surrogate mother?

The study of matching different sets of DNA based on the number of short tandem repeats is called ________.

By inserting four developmental genes into ordinary cells such as skin cells, Shinya Yamanaka and James Thomson were able to convert them into:

In reproductive cloning, cells are subjected to an electric current under special circumstances. What effect does this have?

It is beneficial for children in underdeveloped countries to eat genetically modified "golden rice," rather than regular rice, because golden rice:

Refer to the figure below, and then answer the question that follows. -More than one restriction enzyme can be used to cut a piece of DNA at a time. If you used the restriction enzyme BamHI, which recognizes the sequence GGATCC (shown in the figure), as well as another enzyme that recognizes the sequence AATT, how many DNA fragments would be produced from the DNA strand shown?

A human clone would be as much like the person from whom it was cloned as "identical" twins are like each other.
