Chapter 24, Problem 87A

Interpretation Introduction

Interpretation: Some outcomes of recombinant DNA research are to be explained.

Concept introduction: Recombinant DNA is a hybrid strand of the DNA molecule. The combination of two or more genetic sequences results in the production of recombinant DNA.

Answer to Problem 87A

It is possible to obtain desirable properties in living organisms that were previously lacking by using recombinant DNA. This technique is most commonly used in health and agriculture.

Explanation of Solution

Some outcomes of recombinant DNA research are as follows:

1. Inserting the gene in bacteria responsible for generating human insulin. Before this discovery, pig insulin was used, which is similar to human insulin. But it made some patients sick, so they couldn't use it to control their blood sugar.
2. Medical medications that help patients who have had heart attacks dissolve blood clots were created using technology.
3. Making plants resistant to pesticides and weed killers is used in agriculture. Fruits and vegetables are also improved to make them better for storage and transportation.

Conclusion

It is possible to obtain desirable properties in living organisms that were previously lacking by using recombinant DNA. This technique is most commonly used in health and agriculture.
