Question

Quizplus · Accepted Answer

Gnotobiotic animals are animals that are raised under germ-free conditions or colonized with specific microbiota. These animals are used in laboratory studies to investigate the effects of the microbiota on host physiology, immune function, and disease susceptibility. Tight junctions are cellular structures that form barriers between cells and are not used to study host-microbiota relationships directly. Metagenomics is a technique for studying microbial communities and their genomic composition and is not specific to host-microbiota relationships. Quorum sensing is a mechanism of bacterial communication and is not directly relevant to host-microbiota studies.
