Textbook Question

A specific virus contains RNA as its genetic material.
b. What is the name of this type of virus?

Verified step by step guidance

Understand that viruses can have either DNA or RNA as their genetic material. When a virus contains RNA as its genetic material, it is classified as an RNA virus.

Recall that RNA viruses can replicate using RNA-dependent RNA polymerase or, in some cases, reverse transcriptase if they are retroviruses.

The specific name for a virus that contains RNA as its genetic material is an 'RNA virus.' If the virus uses reverse transcriptase to convert RNA into DNA during replication, it is further classified as a 'retrovirus.'

Ensure you differentiate between RNA viruses and DNA viruses based on their genetic material. This classification is fundamental in virology and helps in understanding their replication mechanisms.

Conclude that the type of virus described in the problem is an RNA virus, based on the information provided.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

RNA Virus

An RNA virus is a type of virus that uses ribonucleic acid (RNA) as its genetic material instead of deoxyribonucleic acid (DNA). These viruses can be single-stranded or double-stranded and are known for their ability to mutate rapidly, which can complicate treatment and vaccine development. Examples include the influenza virus and the human immunodeficiency virus (HIV).

Viral Classification

Viruses are classified based on their genetic material, structure, and replication method. The two primary categories are DNA viruses and RNA viruses. Understanding this classification helps in identifying the virus and determining appropriate treatment strategies, as different types of viruses may respond differently to antiviral drugs.

Viral Replication

Viral replication is the process by which a virus reproduces itself within a host cell. RNA viruses typically enter the host cell, release their RNA, and hijack the host's cellular machinery to produce new viral particles. This process is crucial for the spread of the virus and understanding it is essential for developing antiviral therapies.
