Viruses Flashcard

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 is genetic information in the context of viruses?

Back

Genetic information in viruses refers to the DNA or RNA that carries the instructions for the virus's replication and function.

Front

What is the difference between lytic and lysogenic cycles?

Back

The lytic cycle results in the destruction of the host cell and the release of new viruses, while the lysogenic cycle integrates the viral DNA into the host's genome, allowing it to replicate without killing the host.

Front

What is the role of vaccines?

Back

Vaccines stimulate the immune system to recognize and fight off specific viruses, improving immunity without causing the disease.

Front

What is the seasonal flu virus?

Back

The seasonal flu is primarily caused by the Influenza virus, which changes frequently and can lead to widespread illness.

Front

What is a lytic cycle virus?

Back

A lytic cycle virus is one that replicates by destroying the host cell, releasing new viral particles.

Front

What is a lysogenic cycle virus?

Back

A lysogenic cycle virus integrates its genetic material into the host's DNA, allowing it to replicate along with the host cell without causing immediate harm.

Front

What is the significance of genetic information in both viruses and cells?

Back

Genetic information is essential for the replication and functioning of both viruses and cells, as it contains the instructions for producing proteins and other molecules.

Front

What is the difference between HIV and Influenza in terms of viral reproduction?

Back

HIV reproduces through the lysogenic cycle, integrating its genetic material into the host's DNA, while Influenza reproduces through the lytic cycle.

Front

What is mitosis?

Back

Mitosis is a process of cell division that results in two identical daughter cells, and it is NOT a method of viral reproduction.
