The correct response is: **viral DNA or RNA copied in a host cell**.

Viruses replicate by infecting a host cell and utilizing the host's cellular machinery to reproduce their genetic material and produce new virus particles.

Responses

A provirus is viral DNA incorporated into the host cell’s DNA.
A provirus is viral DNA incorporated into the host cell’s DNA.

A provirus is newly replicated viral DNA after injection.
A provirus is newly replicated viral DNA after injection.

A provirus is the host cell’s DNA that has been destroyed.
A provirus is the host cell’s DNA that has been destroyed.

A provirus is bacterial DNA incorporated into viral DNA.

The correct response is: **A provirus is viral DNA incorporated into the host cell’s DNA.**

A provirus is the form of viral DNA that integrates into the genome of a host cell, allowing the viral genetic material to be replicated along with the host's DNA.

It is caused by retroviruses that insert viral RNA into the host cell's DNA.

It is a spherical-shaped virus with many protein receptors.
GPT-4o mini
The correct response is: **It has a viral genome that mutates very quickly.**

The common cold is caused by several different viruses, including rhinoviruses, which can rapidly mutate. This high mutation rate makes it challenging to create a single effective vaccine for the common cold.
