Lab method
16S rRNA sequencing
Bacterial gene sequencing ID concept
sixteen S R-R-N-A
High-yield clue
Conserved regions anchor amplification; the variable (hypervariable) regions are what distinguish organisms in the database match.
Overview
A molecular identification concept in which conserved regions of the bacterial 16S rRNA gene serve as universal primer sites, and the intervening variable regions are compared with reference databases.
Classification
- Molecular identification concept
- Sequencing vocabulary
Lab & identification clues
