Abstract
The term “RNA sequencing (RNA-Seq)” often means the sequencing of cDNA generated from RNA as well as the direct sequencing of RNA. RNA-Seq has become well known as next generation sequencers emerge, particularly because their high throughput nature of data collection makes RNA-Seq a powerful tool for genome-wide gene expression analysis. In this review, I introduce, mainly from a technical point of view, a basic scheme of RNA sequencing, its development, and its application in several interesting studies.
