Question

Assertion: It is harder to make anti-viral medicine. Reason: Viruses have few blochemical mechanisms of their own. a.Both A and R are true and R is the correct explanation of assertion. b.Both A and R are true but R is not the correct explanation of assertion. c.A is true but R is false. d.A is false but R is true.​

Answer 1

Answer:

a. Both A and R are true and R is the correct explanation of assertion

Explanation:

➝ It is harder to make antiviral drugs rather than antibacterial ones.

➝ The basic structure of viruses are simple with a nucleic acid covered in a protein coat.

➝ Viruses lack a proper cellular organization and their own machinery for metabolism.

➝ They are completely incapable of growth and reproduction outside the host cell.

➝ They utilize the reproductive machinery of the host cells for their division.

➝ They are unaffected by antibiotics and can even undergo mutations by making changes in their nucleic acid structure which makes them resistant to many drugs.

➝ They cannot reproduce outside their host cells and their multiplication involves virulent lytic phase or non virulent lysogenic phase.

➝ The infectivity of a virus is due to its nucleic acid and the specificity of a host is due to its protein coat.

➝ The nucleic acid is the only active part of the virus.

➝ The capsid, the outer protective coat protects the virus from the enzyme nuclease and also helps in the transmission of the viral nucleic acid from one one host to another.

➝ Some viruses contain glycoproteins in their envelope which helps them to bind to the host surface.
