Question

Which of the following is not a reason we often perform metagenomics studies by doing PCR using long degenerate primers for the 16S gene?

   

Eliminates issue of having to randomly fragment DNA for sequencing (which can sometimes be tricky to optimize)

   

All microorganisms have a 16S gene

   

It is taxonomically informative and allows you to identify taxa using a database

   

You can estimate relative taxa abundance by relative read abundance, avoiding genome size bias.

   

You can make a phylogeny allowing you to do diversity analyses

 

   

16S has conserved regions and the primers used allow for some sequence variation, so we can amplify the region from different taxa efficiently using PCR
