RNA-Seq
RNA-Seq (RNA sequencing) is a high-throughput sequencing technique used to analyze the transcriptome of biological samples, quantifying RNA molecules to study gene expression, alternative splicing, and novel transcripts. It involves converting RNA into complementary DNA (cDNA), sequencing it, and mapping reads to a reference genome or assembling them de novo. This methodology is widely applied in genomics, molecular biology, and biomedical research to understand cellular processes, disease mechanisms, and regulatory networks.
Developers should learn RNA-Seq when working in bioinformatics, computational biology, or data science roles focused on genomics, as it is essential for analyzing gene expression data from experiments like cancer studies, developmental biology, or drug response research. It is used to identify differentially expressed genes, detect novel isoforms, and validate hypotheses in fields such as precision medicine, agriculture, and environmental science, requiring skills in data processing, statistical analysis, and visualization.
