Sequencing the genomes present in a biofilm is known as ________.
A. mitochondrial genomics
B. metagenomics
C. pharmacogenomics
D. toxicogenomics
Answer: (B) metagenomics
Explanation:
Metagenomics (also referred to as environmental and community genomics) is the genomic analysis of microorganisms by direct extraction and cloning of DNA from an assemblage of microorganisms.
Interactions among the microbial diversity in the biofilm are complex and play a pivotal role in the pathogenesis of infections. Studies using well-established metagenomic analyses have demonstrated a shift from monomicrobial to polymicrobial biofilm studies in infectious diseases.
