Explain why metagenomics is probably the most revolutionary application of genomics.
Metagenomics is revolutionary because it replaced the practice of using pure cultures. Pure cultures were used to study individual species in the laboratory, but did not accurately represent what happens in the environment. Metagenomics studies the genomes of bacterial populations in their environmental niche.
How can genomics be used to predict disease risk and treatment options?
Genomics can provide the unique DNA sequence of an individual, which can be used for personalized medicine and treatment options.
