Quizplus · Accepted Answer

Metagenomic sampling involves directly sequencing DNA from environmental samples, without the need for culturing the microorganisms present. This allows for the identification and genetic characterization of a vast number of microorganisms that would otherwise not be accessible through traditional cultivation methods. Column chromatography, gas chromatography, Western blot analysis, and ELISA assays are all laboratory techniques that do not necessarily involve genetic characterization without culturing.
