Question
Chapter 21.1, Problem 1TQ
Summary Introduction
To review:
The selection of optimal and suitable DNA (Deoxyribonucleic acid) extraction method for performing a metagenomic analysis of soil samples taken from various parts of wetlands.
Introduction:
Metagenomics involves the study of genetic material that is recovered directly from the environment. Analysis of metagenomic sequencing has posed severe challenges to most of the scientific researchers as this analysis has to follow a complex structure of steps. While doing so the researchers have to face environmental oriented hazards and also have to choose an appropriate target community.

There are many other applications in which DNA barcoding might be useful. For example, how might ecologists use DNA barcoding to find out what species are present in a rain forest, or what kinds of animals a predator eats?
If the PCR analysis of your sample did not work can you suggest why? How can you test if this is true?
What would you conclude if you attained nested PCR product for the genomic Arabidopsis control, but not your plant sample? Give one reasonable explanation and be specific.
