Virus review

Front

What happens to the host cell during a lytic infection by a virus?

Back

The host cell is destroyed.

Front

What takes over the functions of a living cell when a virus invades it?

Back

The virus's genetic material.

Front

What is the first step of virus infection?

Front

What is the purpose of the protein coat surrounding a virus?

Back

To protect the virus and react with the cell wall of the host cell.

Front

What feature do viruses share with animal cells?

Back

Presence of genetic code in nucleic acid.

Front

What is a virus?

Back

A virus is a microscopic infectious agent that can only replicate inside the living cells of an organism.

Front

What are the two main types of viral replication cycles?

Back

Lytic cycle and lysogenic cycle.

Front

What occurs during the lytic cycle?

Back

The virus infects a host cell, replicates, and causes the cell to burst, releasing new viruses.

Front

What is the lysogenic cycle?

Back

A viral replication cycle where the virus integrates its genetic material into the host cell's DNA and remains dormant.

Front

How do viruses differ from living cells?

Back

Viruses cannot reproduce on their own and lack cellular structures.
