Answer:
Meta genomic sampling is the direct genetic analysis of genomes contained with an environmental sample.
Step-by-step explanation:
The statements that correctly describe the genomic sampling of the biosphere are;
- As by carrying out meta genomic sampling we can be provided with the data of functional gene composition of microbial communities.
- Sufficient amounts of high-quality nucleic acids must be obtained for subsequent library production and sequencing.
- The DNA extracted should be representative of all cells present in the sample.
- Two strategies can be employed for meta genomics samples: reference-based assembly (co-assembly) and de novo assembly.
- De novo assembly typically requires larger computational resources.
- The "clonal" assumptions built into many assemblers might lead to suppression of contig formation for certain heterogeneous taxa at specific parameter settings.
