FAQs on Detailed Overview: Structure of Virus & Viral Diseases Video Lecture - Biology Class 11 - NEET
| 1. What is the structure of a virus? |  |
Ans. The structure of a virus consists of genetic material, either DNA or RNA, enclosed in a protein coat called a capsid. Some viruses also have an outer envelope made up of lipids. The genetic material carries the instructions for the virus to replicate and infect host cells.
| 2. How do viruses cause diseases? | |
Ans. Viruses cause diseases by invading host cells and taking over their machinery to replicate. This can lead to cell damage or death. The immune system responds to the viral infection, causing inflammation and other symptoms associated with viral diseases.
| 3. What are some common viral diseases? | |
Ans. Some common viral diseases include the flu, common cold, HIV/AIDS, hepatitis, measles, mumps, rubella, chickenpox, and herpes. Each of these diseases is caused by a specific virus and has its own set of symptoms and complications.
| 4. Can viral diseases be treated with antibiotics? | |
Ans. No, antibiotics are not effective against viral diseases. Antibiotics are designed to kill or inhibit the growth of bacteria, which are different from viruses. Antiviral medications are used to treat certain viral infections, but prevention through vaccination is often the best approach for many viral diseases.
| 5. How can viral diseases be prevented? | |
Ans. Viral diseases can be prevented through various measures such as vaccination, practicing good hygiene, avoiding close contact with infected individuals, and using barriers like face masks and condoms when necessary. Additionally, maintaining a strong immune system through a healthy lifestyle can help reduce the risk of viral infections.
