Viruses have structures that allow them to inject their genetic material directly into the DNA of the host cell. This strategy benefits the virus in that –

the host cell is turned into a virus.

mutations are introduced into the host cell.

it is able to transform into a host cell.

the virus uses the host’s machinery to replicate.

Viruses use two different cycles of replication, the lytic cycle and the lysogenic cycle. In what way is the lysogenic cycle different from the lytic cycle?

The virus recognizes and attaches to host cell.

The host cell is not destroyed immediately.

Viral DNA is replicated along with host DNA.

The virus injects its DNA into the host cell..

A bacteriophage is a type of virus that infects only a bacterial host cell. A bacteriophage can’t cause disease in humans because it –

does not have the correct surface proteins for attachment.

can only use bacterial DNA to replicate.

gets destroyed in the human digestive tract.

is able to reproduce without a host cell.
