A researcher is involved in the production of insulin through recombinant DNA technology. Which of the following statements could the researcher best provide as a rationale for her work?

A)
The gene fragment responsible for insulin production can be isolated and reproduced.
B)
Particular bacteria are capable of insulin production.
C)
It is possible to reproduce the chromosome responsible for insulin production.
D)
Recombination of DNA base pairs can result in a gene that will produce insulin.

Question 2

A patient with malignant melanoma has been prescribed alpha interferon, a biologic response modifier.

Since this drug prolongs the cell cycle, increasing the percentage of cells in the G0 phase, and stimulates NK cells and T-lymphocyte killer cells, the nurse can anticipate that he may experience which of the following common side effects?
A)
Fever, chills, and fatigue
B)
Nausea, vomiting, and diarrhea
C)
Opportunistic infections like Candida
D)
Renal damage with an increased creatinine level

Answer to Question 1

Ans:
A

Feedback:

The gene fragment that initiates and controls the production of several human proteins, including insulin, can be identified, separated, and reproduced by recombinant technology. Bacteria are used as a medium of reproduction, but they are not inherently capable of insulin production. Recombinant technology does not take place at the macrochromosomal level or at the micro- base pair level.

Answer to Question 2

Ans:
A

Feedback:

Interferon is a biologic response modifier that changes a person's own immune response to cancer. This medication is given by injection, usually every other day. Because of stimulation of the body's natural immune response, the patient experiences extreme flulike symptoms.
