Ch 34: Biological Knowledge & Society

About This Chapter

Refresh your memory about biological knowledge and society by opening this chapter. These lessons offer a self-guided method for reviewing important biology topics, terms, and definitions, giving you the opportunity to go over and master all of this information at your own speed.

Biological Knowledge & Society - Chapter Summary

Follow along in this chapter as our instructors elaborate on biological knowledge and societal issues. Many of the lessons talk about major breakthroughs in biological studies, such as the discovery of DNA components. You will also get an overview of the technology that has been invented to study genetic traits and markers.

While these lessons address the science of biology breakthroughs, they also discuss the societal reactions to these discoveries. For example, a few of the lessons go over the controversies that have arisen as a result of scientists altering genetic traits. When you have reached the end of the chapter, you will be ready to:

  • Point out DNA technology practical applications and safety concerns
  • Show the pros and cons of genetic selection, cloning, and genetically modified food
  • Establish the different types of global health issues
  • Offer examples of medical treatments used for pathogen control
  • Determine the role of rational drug design
  • Outline the side effects and types of antibiotics
  • Figure out what problems may be caused by antibiotic resistance
  • Evaluate the impact of antiviral drugs on common viruses and the flu

Several of the lessons in this chapter are in the form of videos. Although each of our video lessons is short in duration, they are still full of valuable information that you need to know to understand these biology topics. In the videos, our instructors discuss the subject matter of each lesson, and on screen you will see key terms, definitions, and other helpful visual aids.

Practical Applications & Safety Concerns of DNA Technology

1. Practical Applications & Safety Concerns of DNA Technology

Our discovery of DNA was a big deal, but what technologies has it led to? And could they be dangerous? Learn about DNA technology, and then test your knowledge with a quiz.

Genetic Selection: Definition, Pros & Cons

2. Genetic Selection: Definition, Pros & Cons

When it comes to the genetic traits of a population, 'selection' is the process that chooses those traits. Artificial genetic selection is controversial, especially when it comes to human beings. This lesson defines genetic selection and discusses the pros and cons of artificial genetic selection.

Pros & Cons of Cloning

3. Pros & Cons of Cloning

In this lesson, we'll explore the major pros and cons of cloning. Before we get into the meat of the lesson, we'll review what cloning is, and then we will look at examples of how cloning could benefit society and some reasons we might need to hold off.

Pros & Cons of Genetically Modified Food

4. Pros & Cons of Genetically Modified Food

This lesson is on the pros and cons of genetically modified foods. We'll learn what genetically modified food is as well as some of the benefits and concerns regarding it.

Types of Global Health Issues

5. Types of Global Health Issues

The following lesson will define what a global health issue is and discuss the cause for their spreading, as well as provide examples of major global health issues. A short quiz will follow the lesson.

Medical Treatments to Control Pathogens

6. Medical Treatments to Control Pathogens

This lesson covers the different categories of medical treatments to control pathogens. We'll look at mechanisms of actions and examples of antibiotics, antivirals and antifungals, as well as the infections they're commonly used to treat.

Rational Drug Design: Definition & Role

7. Rational Drug Design: Definition & Role

This lesson explains the fundamental concepts behind rational drug design. You'll also learn how these concepts apply to a real-world example in zanamivir.

What Are Antibiotics? - Definition, Types & Side Effects

8. What Are Antibiotics? - Definition, Types & Side Effects

Antibiotics are medicines created to fight infections caused by bacteria. They accomplish this by destroying the bacteria in a variety of ways. Learn more about how antibiotics work and take a short quiz at the end.

Antibiotic Resistance: Definition, Types & Problems

9. Antibiotic Resistance: Definition, Types & Problems

If you have a bad bacterial infection, what do you do? Go to the doctor and get antibiotics, of course. But, what if antibiotics don't work anymore because the bacteria are antibiotic-resistant? In this lesson, learn how bacteria can become resistant to antibiotics and why this is such a big problem.

Antiviral Drugs: Treatments for Flu & Other Common Viruses

10. Antiviral Drugs: Treatments for Flu & Other Common Viruses

You may have heard that viruses are not even considered to be alive, but they sure can cause a lot of damage when they infect us! Learn how antiviral drugs can selectively inhibit viruses even though they use our own cellular machinery to reproduce.
