Virus Biology Quiz

Study Notes

True or False Statements

Viruses reproduce inside the cells of living hosts: True
Viruses have cells that divide: False
Viruses contain genes, which allow them to mutate and evolve: True
Viruses are made of either two or three parts: True
All viruses are covered with a protein coat to protect the genes: True

Characteristics of Viruses

Viruses are acellular, meaning they do not have a cellular structure.
They require a host cell to replicate and reproduce, utilizing the host's cellular machinery.
Viral genetic material can be DNA or RNA, which enables mutation and evolution.

Origin of Viruses

The exact origin of viruses is unclear; however, theories suggest they may have originated from cellular organisms or existed before the first cells.
Some hypotheses indicate that viruses may have evolved from mobile genetic elements or plasmids.

Purpose of the Protein Coat

The protein coat, or capsid, of a virus serves to protect the viral genetic material from the external environment.
It facilitates the attachment and entry of the virus into host cells.

Virus Reproduction

Viruses reproduce by infecting a host cell and hijacking its machinery to produce new virus particles.
The viral replication cycle typically consists of attachment, penetration, uncoating, replication, assembly, and release.

Types of Genetic Material in Viruses

Two main types of genetic material are found in viruses: single-stranded and double-stranded DNA or RNA.
The type of genetic material influences the virus's method of replication and infection process.
