Summary Introduction

Introduction:

A virus is a small infectious agent that can’t be seen through the naked eyes. Viruses are made up of protein coat in which their genetic material is present. The viruses contain either double stranded or single stranded DNA or RNA as their genetic material.

Answer to Problem 1MCQ

Correct answer:

Cytoplasm is not the feature associated with viruses. Therefore, option a. is correct.

Explanation of Solution

Reason for the correct statement:

The structures of the virus is simple that lacks the basic characteirstics of the cells. It does not have organelles, ribososmes, nucleus, cytoplasm or even a cell membrane.

Option a. is given as “Cytoplasm”.

As, “the feature that is NOT associated with viruses is cytoplasm”, is the right answer.

Hence, option a. is correct.

Reasons for the incorrect statements:

Option b. is given as “Genetic information”.

All the viruses carry genetic material which guide the synthesis of proteins, since it is the feature of viruses. So, it is a wrong answer.

Option c. is given as “Protein coat”.

Protein coat is also known as capsid which surrounds the genetic material, since it is the feature of viruses. So, it is a wrong answer.

Option d. is given as “Envelope”.

Envelope is protein and lipid rich outer layer. It is derived from the host’s cell embrane parts, since it is the feature of viruses. So, it is a wrong answer.

Hence, option b., c., and d. are incorrect.

Conclusion

The viral structure lacks cytoplasm. Thus this feature is not associated with viruses.
