Q & A

What is the first beneficial role of viruses mentioned in the transcript?

The first beneficial role of viruses discussed is gene therapy, specifically using retroviruses as vectors to introduce the gene encoding the enzyme adenosine deaminase (ADA) into abnormal T lymphocyte cells to treat genetic disorders like ADA deficiency.

What condition does ADA deficiency lead to?

ADA deficiency leads to a lack of immune system strength, resulting in a severe immune deficiency since the body cannot produce the necessary enzyme.

How are viral proteins used in vaccine development?

Viral proteins, specifically the capsid proteins, can be utilized to stimulate an immune response, helping the body to recognize and fight off the disease effectively.

What type of biological treatment involves using viruses to combat pathogens?

Biological treatment refers to the use of bacteriophages, which are viruses that specifically attack bacteria, to kill pathogenic bacteria, fungi, or protozoa.

What is the function of bacteriophages?

Bacteriophages function by targeting and killing specific bacteria, making them a potential treatment for bacterial infections, especially those resistant to antibiotics.

What is a bioinsecticide?

A bioinsecticide is a natural insecticide derived from biological organisms, such as certain viruses, used to control pest populations without harming the environment.

What is the significance of using viruses in pest control?

Using viruses in pest control is significant because it provides an environmentally friendly alternative to chemical pesticides, reducing pollution and potential harm to non-target organisms.

What will the next topic discussed in the session be?

The next topic will cover the detrimental roles of viruses, contrasting the previous discussion about their beneficial aspects.

What kind of response is triggered by vaccines using viral proteins?

Vaccines using viral proteins trigger an immune response, training the immune system to recognize and fight the pathogen if encountered in the future.

What is the overall message of the session regarding viruses?

The overall message is that while viruses are often associated with negative effects, they also have significant beneficial roles in medical and environmental applications.
