RNA-Seq Analysis
Save
RNA-Seq analysis is a powerful technique that allows scientists to study the expression of genes in a cell or tissue. It is a valuable tool for understanding gene regulation, identifying biomarkers, and diagnosing diseases. RNA-Seq analysis is a complex process that involves a number of steps, but it can be broken down into four main stages:
Data generation
The first stage of RNA-Seq analysis is data generation. This involves collecting RNA from cells or tissues and converting it into a library of cDNA fragments. cDNA is complementary DNA, which is a single-stranded DNA molecule that is synthesized from an RNA template. The cDNA library is then sequenced using a high-throughput sequencing platform.
Data analysis
The next stage of RNA-Seq analysis is data analysis. This involves aligning the sequenced cDNA reads to a reference genome and quantifying the expression of genes. Gene expression is typically measured in terms of fragments per kilobase of transcript per million mapped reads (FPKM). Differential expression analysis can be used to identify genes that are differentially expressed between different samples.
