Q & A

What is the general perception of viruses in relation to human health?
-The general perception of viruses is that they are harmful, often associated with causing diseases like the common cold, flu, and influenza.
Can viruses play a beneficial role in our lives? If so, how?
-Yes, viruses can play beneficial roles such as in vaccine production, virotherapy for cancer treatment, and in the production of antitoxins and insulin.
How do vaccines help in combating diseases?
-Vaccines help by introducing weakened or inactivated viruses into the body, allowing the immune system to recognize and create antibodies against them, so the body is prepared to fight off the actual virus if exposed.
What is virotherapy and how does it benefit cancer treatment?
-Virotherapy is a treatment that uses viruses to target and kill cancer cells. Scientists use the virus's natural ability to infect cells to deliver a 'killing effect' specifically to cancer cells.
How are viruses used in the production of antitoxins and insulin?
-Viruses are used to produce antitoxins and insulin by combining their DNA with beneficial genes. This DNA is then introduced into bacteria, which produce the desired substances such as insulin when they multiply.
What role do viruses play in agriculture, and how do they benefit crop health?
-In agriculture, viruses can be used as biological control agents against pests. For example, baculoviruses can infect and control pests that damage crops.
How do viruses impact human health negatively?
-Negatively, viruses can cause various diseases such as influenza, mumps, polio, chickenpox, measles, and rabies, which can lead to severe health complications.
What are some diseases that viruses can cause in animals?
-Viruses can cause diseases in animals such as Newcastle disease in poultry, foot-and-mouth disease in livestock, and rabies in dogs, cats, and monkeys, which can also infect humans.
How do viruses harm plants, and what are some examples of plant diseases caused by viruses?
-Viruses can cause diseases in plants, such as tungro virus in rice, which stunts growth, and tobacco mosaic virus, which causes mottling on tobacco leaves. Citrus vein phloem degeneration is another example that affects the vascular system of citrus plants.
How do scientists study viruses to understand their roles in molecular and cellular biology?
-Scientists study viruses to understand processes like DNA replication, transcription, RNA formation, protein formation, and other aspects, which are crucial for future advancements, particularly in the field of health.
What is the importance of understanding both the harmful and beneficial roles of viruses?
-Understanding both the harmful and beneficial roles of viruses is important for developing treatments and preventive measures against diseases, as well as harnessing their potential for medical and agricultural advancements.
