Intronic reads
WebSep 3, 2024 · At the same time, one potential weakness of this approach is the possibility of DNA contamination, with genomic DNA also being tagmented and processed along with the rest of the RNA and leading to high amounts of intergenic and intronic reads. Libraries generated using this method also tended to have slightly higher rates of duplicate reads. WebThe intronic reads likely originate from immature transcripts which include either full-length pre-mRNA molecules or nascent transcripts where the RNA polymerase has not yet …

WebApr 6, 2024 · RNA-seq (RNA-sequencing) is a technique that can examine the quantity and sequences of RNA in a sample using next-generation sequencing (NGS). It analyzes the transcriptome, indicating which of the genes encoded in our DNA are turned on or off and to what extent. Here, we look at why RNA-seq is useful, how the technique works and the … elearning dhbw.dfood near me berry farmsWebIntronic reads could be due to 1) immature transcripts with introns not spliced out yet 2) unannotated exons which might represent alternative splicing, if the sequence and … food near me bentonvilleWebRaw sequence reads were aligned to the human reference genome 19 using Burrows Wheelers Aligner [11], and duplicate reads were removed using Picard (Broad Institute).
