RNA-seq analysis is a method used to analyze the transcriptome of a cell or tissue sample. This technique involves sequencing RNA molecules to determine which genes are being actively expressed at a given time. By comparing the levels of different RNA transcripts, researchers can gain insight into the genes and pathways that are involved in various biological processes. RNA-seq analysis can be used to study gene expression patterns, identify novel transcripts, detect alternative splicing events, and assess differential gene expression between different conditions or treatments. This research area has revolutionized our understanding of gene regulation and has been widely used in fields such as genomics, molecular biology, and biomedical research.
