Question

Diagram of Adenovirus.
Choose the correct for the given diagram.

• A. Bacteriophage - Tobacco mosaic disease
• B. Adenovirus - Cause of respiratory disease
• C. Viroid - Potato spindle tumour disease
• D. Prion - Alzheimer's disease

Answer 1

The correct option is B Adenovirus - Cause of respiratory disease

• Adenoviruses are a group of viruses that typically cause respiratory illnesses, such as a common cold, conjunctivitis (infection in the eye), bronchitis, or pneumonia. In children, adenoviruses usually cause infections in the respiratory tract and intestinal tract.
  
• The Potato spindle tuber viroid was the first viroid to be identified. It is a small, single-stranded circular RNA molecule, infecting potatoes and tomatoes.
  
• Tobacco mosaic disease is caused by the bacteriophage Tobacco mosaic virus, a single stranded RNA virus. It infects a wide range of plants, especially tobacco and other members of the family Solanaceae. The infection causes characteristic patterns, such as "mosaic"-like mottling and discoloration on the leaves.
• A prion is a type of protein that can trigger normal proteins in the brain to fold abnormally, leading to diseases like Alzheimer's disease and Creutzfeldt-Jakob disease (CJD).
