3omics

Definition

3omics refers to the integration of three major omics fields: genomics, transcriptomics, and proteomics. This holistic approach allows researchers to examine the complex interactions between genes, RNA transcripts, and proteins, providing a more comprehensive understanding of biological systems and disease mechanisms. By analyzing these three layers together, scientists can uncover how genetic information translates into functional proteins, leading to insights in areas like personalized medicine and biomarker discovery.
