WebIt involves copying a gene's DNA sequence to make an RNA molecule. Transcription is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template). Transcription has three stages: initiation, elongation, and termination. WebIf total RNA is sequenced, about 90% of RNA-seq reads will be ribosomal, leaving only ~10% of reads relevant to your experiment. If rRNA is 97% depleted, the fraction of relevant reads increases to almost 80%. By …
