Answer:

The correct answer is C. In the plaque assay for bacteriophages, the plaque is a clear zone caused by a zone of lysis.

Explanation:

The plaque assay is an approach used for titering bacteriophage stocks or determining the quantity of infectious virus in a sample. Plaques are visualized if you spot the phage on a lawn of growing compatible bacteria. Each plaque indicates an initial infection with one phage followed by lysis of neighboring bacteria in the lawn. Only viruses that cause visible damage of cells can be assayed in this way. The plaque assay is used to determine viral titer as plaque-forming units per ml so that known amounts of virus can be used to infect cells during subsequent work.

In the plaque assay for bacteriophages, the plaque is a clear zone caused by a zone of lysis.

What usually happens to the host’s DNA during the lytic cycle?
QveST [7]

Answer:

The correct answer is -

A.It is destroyed.

Explanation:

The lytic cycle is considered as one of the two reproductive cycles that virus use for its reproduction (the other cycle is the lysogenic cycle).

This cycle results in the destruction of the host cell.

Bacteriophages (virus that infects bacteria)  use this cycle and referred as virulent phages.

There are basically five steps in this cycle -

Attachment of virus with the host cell membrane, penetration of the genome, which is followed by biosynthesis using host machinery, assembly of virus particles, and finally release, causing host cell destruction.

Thus, option A is the right answer.
