This is due to recently developed methods for strand-specific protocols, allowing for the distinction of transcripts that overlap protein coding genes on the opposite strand (for example. RNA Capture Long Seq (CLS) is a new method for transcript annotation that combines targeted RNA capture with long-read sequencing. There is a great variety of ncRNAs with a versatile function in prokaryotes and eukaryotes, but this chapter will focus on those ncRNAs that play a. Finally, an example of interaction among different types of RNA (long non-coding, genes, microRNAs) has been reported, showing the complexity of the pathways that regulate the life of cells. Long non-coding RNAs: Insights into functions. In recent years, the pace of discovery of novel ncRNAs and their cellular roles has been greatly accelerated by high-throughput sequencing.
