A

It allows for rapid identification of pathogens by comparing genetic markers against a database of sequences.

B

It provides a method for visually observing bacteria under a microscope.

C

It replaces all traditional methods of bacterial culture and identification.

D

It is primarily used for identifying viral pathogens rather than bacterial ones.

Understanding the Answer

Let's break down why this is correct

Sequencing reads the 16S rRNA gene, which is present in all bacteria but has unique regions for each species. Other options are incorrect because Sequencing does not give a picture of the bacteria; Sequencing is a tool, not a replacement for culture.
