A

To classify bacterial species based on genetic information

B

To determine the antibiotic resistance of bacteria

C

To analyze protein structures in bacteria

D

To measure the growth rate of bacterial colonies

Understanding the Answer

Let's break down why this is correct

16S rRNA sequencing reads a part of the bacterial genome that is very similar across species but has small differences. Other options are incorrect because People think it tells us if bacteria can resist antibiotics, but that requires looking at resistance genes, not the 16S gene; Some believe it analyzes proteins, but 16S sequencing reads RNA, not protein structures.
