RNA, Long Noncoding RNA, Untranslated RNA-Seq is an approach to transcriptome profiling that uses deep-sequencing technologies to detect and accurately quantify RNA. 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. There are several types of non-coding linear RNAs such as microRNAs (miRNA) and long non-coding RNAs (lncRNA), as well as circular RNAs (circRNA) consisting of a closed continuous loop. Background. Genomes are extensively transcribed and give rise to thousands of long non-coding RNAs (lncRNAs), which are defined as RNAs longer than 200 nucleotides that.
