What Are Viruses? - Definition, Structure & Function

1. What Are Viruses? - Definition, Structure & Function

In this lesson, you'll learn some historical facts about viruses and the material they are composed of. Find out more as we review the capsid, nucleic acids, the viral envelope, viruses, virions, bacteriophages and virology.

The Life Cycle of a Virus: How Viruses Live, Attack & Replicate

2. The Life Cycle of a Virus: How Viruses Live, Attack & Replicate

Find out how viruses infect and replicate as we explore the important steps of the virus life cycle, including attachment, uncoating, penetration, replication, and release, as well as the lysogenic and lytic cycles.

Classification of Viruses: Viral Genome and Replication Scheme

3. Classification of Viruses: Viral Genome and Replication Scheme

Find out how viruses are classified based on their being double-stranded, single-stranded, positive-sense, negative-sense, or by having something called reverse transcriptase.

Replication of DNA Viruses

4. Replication of DNA Viruses

This lesson will give you a basic overview of how DNA viruses replicate inside of a host cell. We will cover the entry, integration, replication and release of DNA viruses.

Replication of RNA Viruses

5. Replication of RNA Viruses

This lesson will give you a basic overview of how different types of RNA viruses replicate inside of an animal cell. We will cover the essence of being double-stranded and retroviruses, as well as positive-and negative-sense RNA viruses.

Viruses: Bacteriophage Lytic and Lysogenic Cycles

6. Viruses: Bacteriophage Lytic and Lysogenic Cycles

Viruses are generally not only our enemy but also the enemy of many other organisms. Bacteriophages are viruses that infect specific bacteria. In this lesson, we'll discuss their basic structure and infection cycle.

The Different Routes of Infectious Disease Transmission

7. The Different Routes of Infectious Disease Transmission

This lesson will discuss the different ways you can get sick. We'll discuss how pathogenic microbes can be transmitted to you or someone else as we explore horizontal and vertical transmission as well as vectors, vehicles, and fomites.

The Adenoviridae Virus Family: Infections of Head, Chest & Abdomen

8. The Adenoviridae Virus Family: Infections of Head, Chest & Abdomen

In this lesson, we'll talk about how the Adenoviridae virus family causes gastroenteritis, why adenovirus 14 is dangerous, and what vertical and horizontal transmission is, as well as something disgusting called the orofecal route.

Liver Cancer and Hepatitis B: Hepadnaviridae Structure, Transmission & Disease

9. Liver Cancer and Hepatitis B: Hepadnaviridae Structure, Transmission & Disease

This lesson will cover the structure, mode of transmission and diseases associated with the Hepadnaviridae family of viruses, including the hepatitis B virus, hepatocellular carcinoma, cirrhosis and oncogenesis. We'll also cover the hepatitis D virus and its effects on your body.

Chickenpox, Herpes, and Mono: Diseases of the Herpesviridae Virus Family

10. Chickenpox, Herpes, and Mono: Diseases of the Herpesviridae Virus Family

Learn about the infamous diseases that the viruses of the Herpesviridae family cause. You've probably heard of most of them: chickenpox, shingles, mono, and cold sores. Learn about the viruses such as the herpes simplex, varicella zoster, and Epstein-Barr virus that cause these conditions.

The Stomach Flu & Viruses of the Caliciviridae Virus Family

11. The Stomach Flu & Viruses of the Caliciviridae Virus Family

In this lesson, you'll learn about the most common cause of the stomach flu. We'll venture into the Caliciviridae virus family, its famous viruses, such as the Norwalk virus, as well as the diseases they cause.

HIV and AIDS: Mechanisms and Diseases of the Retroviridae Virus Family

12. HIV and AIDS: Mechanisms and Diseases of the Retroviridae Virus Family

Learn about one of the most famous viruses in the world: HIV. We'll also delve into a condition you've almost certainly heard of: AIDS. Finally, we'll discuss the mechanisms of how viruses in this family cause so much damage and if there's anything you can do about it.
