Transcriptomics connects the genome to its gene function. Where genomes show what could happen, transcriptomics can tell what appears to be happening.
We all learned that genomes show what could happen and that transcriptomics (and proteomics) tells us what is happening at a certain point in time. The analysis of transcriptomes allows the identification of candidate genes and of expressed markers associated to traits of interest. The transcriptome is often a good starting point for your biomarker or assay signature analysis. With the single cell transcriptomics application, transcriptomics has become top of mind again in the scientific community.
