V1-V2
V3-V4
V5-V6
V8-V9
What does alpha diversity in 16S amplicon sequencing data represent?
Differences between microbial communities
Richness and evenness within a single microbial community
Functional capabilities of the microbiome
Evolutionary relationships between bacterial species
Which of the following factors does NOT typically affect the outcome of 16S amplicon sequencing experiments?
DNA extraction method
PCR amplification bias
Choice of variable regions sequenced
The phase of the moon during sample collection
The 16S rRNA gene is approximately (a) base pairs in length.
In 16S amplicon sequencing, (a) diversity measures the differences between microbial communities.
The (a) index is a commonly used alpha diversity metric that accounts for both richness and evenness of a microbial community.
16S amplicon sequencing cannot reliably identify _______ and _______, which are two major groups of microorganisms besides bacteria and archaea.
(a)
The (a) pipeline is a popular bioinformatics tool for analyzing 16S amplicon sequencing data, which uses amplicon sequence variants instead of OTUs.
Explain why 16S amplicon sequencing might not be suitable for studying closely related bacterial strains within the same species.
How does PCR bias potentially affect the interpretation of relative abundance data from 16S amplicon sequencing experiments?
Describe two ways in which sample preparation can influence the results of a 16S amplicon sequencing experiment.
What is the significance of using mock communities in 16S amplicon sequencing studies?
Explain the difference between OTU-based and ASV-based approaches in 16S amplicon sequencing data analysis.
