Transcriptomics

Definition

Transcriptomics is the study of the complete set of RNA transcripts produced by the genome at any one time. This field focuses on understanding how genes are expressed in different conditions, including health and disease, and can reveal insights about cellular functions and responses. By analyzing RNA profiles, researchers can identify biomarkers for diseases and develop targeted therapies, making it a crucial tool in microbiome-based diagnostics and therapeutics.
