Genomes from metagenomics: pulling the needles from the haystack.

Shotgun whole genome sequencing revolutionized how we study single, microbial isolates. By breaking the genome into small reads in vitro, we are able to parallelize sequencing and decrease costs before bioinformatic assemblers put the puzzle back together again in silico. However, re-building the genomic … Continue reading
