What gene sequences are used to identify the prokaryote organisms present in an environmental sample?
A) 18S rRNA genes
B) 16S rRNA genes
C) 70S rRNA genes
D) 80S rRNA genes
E) All of these

Question

16S rRNA genes are commonly used for identifying prokaryotic organisms present in environmental samples because they are relatively conserved among different bacterial species and yet still have enough variability to distinguish between them. 18S and 80S rRNA genes, on the other hand, are eukaryotic-specific, while 70S rRNA genes are found in both prokaryotes and mitochondria.
