5. As a virulent strain ofstaphylococcus aureus has arisen that is resistant to most you likely know, antibiotics. The strain (methicillin-resistant S aureus or MRSA) is commonly found in hospitals.

Solution

Part 1 Answer:

Metagenomics: Study of genetic material by direct extraction and cloning of DNA from environmental samples.
This field circumvents the unculturability and genomic diversity of most microbes, the biggest roadblocks to advances in clinical and environmental microbiology.

As per Torsten Thomas etc al. the flow diagram of metagenomics :
Exprimental design---> Sampling--->Sample fractionation---> DNA extraction---->DNA Sequencing --
-->Assembly---> Satistical analysis---->Data Starage(metadata)--->Data sharing

Part 2 Answer:

Lab is one part of the metagenomics studies, but a major part of it includes computational analysis and application of statistics. Protocol of metagenomics projects includes lot of statistical approach starting from sample calculation tilll the significae level, so these are much more systematic approach. Most importatantly the data revealed from one experiemnt can be stored in databases and can be used anytime needed.Scientists can easily study new genes from the sequence analysis and bioinformatics approach(using different software tools), which can help us produce new antibiotics.
