SOL Bacteria and Viruses

Front

What is the replication machinery used by viruses and bacteria?

Back

Viruses use host cell machinery to replicate; bacteria have their own replication machinery.

Front

What structures are present in both bacteriophages and coronaviruses?

Back

Both have a capsid and genetic material.

Front

What is a characteristic of the lysogenic cycle in bacteriophages?

Back

The phage inserts DNA into host DNA, forming a prophage.

Front

Which sample most likely identifies viruses?

Back

Sample 3.

Front

What distinguishes viruses from unicellular living organisms?

Back

Genetic material is surrounded by a capsid.

Front

Define a virus.

Back

A virus is a microscopic infectious agent that can only replicate inside a host cell.

Front

What is a bacteriophage?

Back

A bacteriophage is a type of virus that infects bacteria.

Front

What is the lytic cycle?

Back

The lytic cycle is a viral replication process that results in the destruction of the host cell.

Front

What is the difference between the lytic and lysogenic cycles?

Back

The lytic cycle destroys the host cell, while the lysogenic cycle integrates viral DNA into the host's DNA.

Front

What is a prophage?

Back

A prophage is the viral DNA that has been integrated into the host's DNA during the lysogenic cycle.
