Whole Transcriptome Sequencing (rna Seq)
overall review score: 4.5
⭐⭐⭐⭐⭐
score is between 0 and 5
Whole-transcriptome sequencing (RNA-seq) is a revolutionary technology used to analyze the complete set of RNA transcripts in a biological sample. It enables researchers to quantify gene expression levels, identify novel transcripts, detect alternative splicing events, and understand complex regulatory mechanisms at a genome-wide scale. RNA-seq has become a fundamental tool in transcriptomics, functional genomics, and biomedical research, providing insights into cellular processes, disease mechanisms, and responses to treatments.
