RNA-seq

Definition

RNA-seq, or RNA sequencing, is a powerful technique used to analyze the transcriptome, which is the complete set of RNA molecules expressed in a cell or organism. It allows for the identification and quantification of gene expression levels by sequencing the RNA molecules present in a sample.
