Instructions

Check your understanding of concepts from 5·15–5·18 Biotechnology has the potential for improving human health (and criminal justice) by answering the following questions.

1.

1. Which of the following is NOT a product of recombinant DNA technology?

recombinant human growth hormone

recombinant human erythropoietin

recombinant human insulin

recombinant human diabetes

All of the above are products of recombinant DNA technology.

Correct! (See section 5·15 The treatment of diseases and production of medicines are improved with biotechnology.)

Incorrect. (See section 5·15 The treatment of diseases and production of medicines are improved with biotechnology.)

2.

2. Short tandem repeat sequences of DNA:

are produced when a mutation occurs in a sperm-producing or egg-producing cell.

are characteristic of genes that code for biochemical traits, rather than structural traits.

are used in biotechnology when creating a clone.

are produced when a mutation occurs in a non-sex cell.

can be used to produce a DNA fingerprint.

Correct! (See section 5·18 DNA is an individual identifier: the uses and abuses of DNA fingerprinting.)

Incorrect. (See section 5·18 DNA is an individual identifier: the uses and abuses of DNA fingerprinting.)

3.

3. Which of the following is NOT a difficulty that medicine has encountered in its attempts to cure human diseases through gene therapy?

For many diseases, a malfunctioning gene has not been identified.

It is difficult to get the working gene into the specific cells where it is needed.

The transfer organism—a bacterium or virus—may get into unintended cells and cause disease.

It is difficult to get the working gene into enough cells at the right rate to have a physiological effect.

All of the above are difficulties that medicine has encountered in its attempts to cure human diseases through gene therapy.

Correct! (See section 5·16 Gene therapy: biotechnology can help diagnose and prevent diseases, but has had limited success in curing them.)

Incorrect. (See section 5·16 Gene therapy: biotechnology can help diagnose and prevent diseases, but has had limited success in curing them.)

4.

4. Some forms of dwarfism in children can be treated by ___________________ made by recombinant DNA techniques.

insulin

erythropoietin

Bacillus thuringiensis

clones

human growth hormone

Correct! (See section 5·15 The treatment of diseases and production of medicines are improved with biotechnology.)

Incorrect. (See section 5·15 The treatment of diseases and production of medicines are improved with biotechnology.)

5.

5. The technique often used in forensics that identifies individuals based on their genetic differences is referred to as:

DNA screening.

DNA fingerprinting.

DNA cloning.

DNA analyzing.

DNA typing.

Correct! (See section 5·18 DNA is an individual identifier: the uses and abuses of DNA fingerprinting.)

Incorrect. (See section 5·18 DNA is an individual identifier: the uses and abuses of DNA fingerprinting.)
