A researcher studying a microbial community in a polluted river uses metagenomics to identify the microbial species present. However, the community contains many low-abundance species that are hard to detect. Which approach would help to improve the detection of these rare species?

Question

Answer

Use short-read sequencing to increase sample throughput

Answer

Focus only on RNA sequences from the most abundant species

Answer

Increase sequencing depth to capture more reads from rare species

Answer

Limit analysis to dominant species to simplify data processing
