This is a fundamental challenge for differential expression (DE) analysis. Transcription is the first step of gene expression. 2). One group of non-coding regulatory regions are enhancers, which can be distantly located upstream or downstream of genes and which can mediate temporal and tissue-specific transcriptional control via long-distance interactions with promoter regions. The key aims of transcriptomics are: to catalogue all species of transcript, including mRNAs, non-coding RNAs and small. A 2007 study on non-coding transcripts in human and mouse first used the term “long” to refer to transcripts of over 200 nucleotides (Kapranov et al, 2007), and this classification became.
