Question
Chapter 17, Problem 1TY
Summary Introduction
Introduction:
The protein coat of the virus is classified according to its structure. Some viruses have envelop that means a lipid membrane that is called capsid. There are various types of protein coat such as icosahedral, helical, prolate.
Expert Solution & Answer
Answer to Problem 1TY
The correct answer is option (c) capsid.
Explanation of Solution
Explanation/justification for the correct answer:
Option (c) capsid. A capsid is a protein covering of a virus. The structural subunit of proteins is protomers. The genetic material is enclosed within the capsid. The helical and icosahedral capsids are found in the majority of viruses. So, the correct answer is an option (c).
Explanation for incorrect answer:
Option (a) host.Viruses are dependent on the host or living cells for the process of reproduction. Hence, the given option is not correct.
Option (b) Prions. Prions are protein particles that cause disease, and prions are not the component of the virus. Hence, the given option is not correct.
Option (d) viroid. Viroids are an infectious particle, smaller than viruses. Hence, the given option is not correct.
Option (e) cell wall. A virus does not contain a cell wall. Viruses have a protein coat instead of a cell wall. Hence, the given option is not correct.
