Question

Which are the six stages of the growth of viruses in the correct sequential order?

Answers

  1. Penetration, attachment, uncoating, replication, self-assembly, release.
    • Rationale:

      This is not the correct sequential order for the replication of viruses.

  2. Uncoating, attachment, penetration, replication, self-assembly, release.
    • Rationale:

      This is not the correct sequential order for the replication of viruses.

  3. Replication, attachment, penetration, uncoating, self-assembly, release.
    • Rationale:

      This is not the correct sequential order for the replication of viruses.

  4. Attachment, penetration, uncoating, replication, self-assembly, release.
    • Rationale:

      This is the correct sequential order for the replication of viruses. The order is attachment, penetration, uncoating, replication, self-assembly, and release.

Overview

Viruses are an infective agent that consists of a nucleic acid molecule in a protein coat.

Explanation

Learning Outcomes

A virus is smaller than bacteria. They are able to multiply within the living cells (i.e., a host). The six stages of virus growth in the correct sequential order are as follows:
Attachment
Penetration
Uncoating
Replication
Self-assembly
Release.

Test Taking Tip

Sequential indicates that the correct answer must be in the order in which viral growth occurs.
