Exam 22: Biotechnology

Which of the following mechanisms uses high-velocity microprojectiles, coated with DNA, to produce a transgenic plant?

Hematopoietic stem cells are ________.

The first hormone to be made by recombinant bacteria was ________.

Which of the following is not an advantage of a transgenic plant?

An organism that can be regenerated by somatic cells is called multipotent.

All stem cells have the potential to differentiate

A transgenic organism has recombinant DNA integrated into its genome.

The primary interest of genetic research into stem cells is the desire to be able to clone a human being.

By creating gene knockouts, researchers can study how the loss of normal gene function affects the organism

When researchers produced a gene knockin by introducing the mutant human β-globin gene into mice, the resulting mice showed very severe symptoms of the disease.

In the treatment of ADA deficiency and SCID, which cell type was targeted for gene therapy?

Which of the following can be used as a vector for gene therapy?

In the production of transgenic plants, what selectable marker is most commonly used to indicate that a cell has taken up the T DNA that includes the cloned gene?

A major disadvantage with current gene therapy techniques using viral vectors is the possibility of an immune response against the virus.

Bone marrow transplants typically use what type of cells?

Which of the following organisms is used by molecular biologists to produce transgenic plants?

Identical twins are an example of gene cloning.
