Exam 20: DNA Technology and Genetic Engineering

Manipulation of the genetic makeup of cells or whole organisms is known as

Which one of the following genetically engineered vaccines is presently on the market?

Each of the following is used in the process of DNA sequencing EXCEPT which one?

Gene therapy is a technique in which DNA from one species is inserted into another to produce useful gene products.

During DNA replication, a(n) ________ added to a DNA template serves as the beginning site of nucleotide addition.

Both plants and animals can be manipulated to generate transgenic organisms, but the process is much easier with plants. Explain why it is more difficult to generate transgenic animals than plants.

Genetically engineered plants that contain high levels of beta-carotene are especially important additions to the diet because beta-carotene is converted to ________ in the human body.

Transgenic plants can presently be used for the production of human proteins, including human serum albumin.

After a strand of DNA has been cut with restriction enzymes, the pieces are attached again by the action of

Plasmid DNA from humans has been successfully inserted and expressed in bacteria.

Through genetic engineering, it is possible for scientists to identify the sequence of bases in DNA, determine the location of certain genes in DNA, and create more DNA from DNA samples.

One of the main problems associated with treating human diseases through gene therapy is

A(n) ________ is a sequence that reads the same from left to right on one strand of DNA as it does from right to left on the other strand.

Transgenic bacteria are presently used to produce ________ that can be administered to humans or other animals to prepare the immune system for a possible infection by a disease-causing organism.

Restriction enzymes are used in genetic engineering to cut DNA between specific base pairs in a DNA strand, resulting in DNA segments that are then used for further study and analysis.

Which one of the following is an example of "gene pharming"?

The first successful treatment of a human genetic disorder through gene therapy was with a disorder known as

Prior to genetic engineering, insulin for humans with insulin-dependent diabetes was extracted from pigs and cattle. Presently insulin is produced by transgenic

Pharmaceutical companies prefer to genetically engineer large animals with human genes because it may be possible to obtain large amounts of the resulting protein from the animals'

Once a genetic disorder in an adult is treated successfully through gene therapy, it is highly unlikely that the person's children will inherit the gene(s) for the disease.
