text: user9656: I am studying about RNA seq, and especially about 3'Quantseq(tagseq, 3primeseq). I wonder if there is a cutoff for the reads length. By this I mean that given that 3'quantseq targets the end of the genes and 3'UTR, then for example if reads are 75bp, then could be the case that only 3'UTR is mapped and not coding region? I am interested in Human Sapiens. Thank you in advance.
  
  user-1: Simple answer: Yes, that can very well happen depending on the average fragment size, the read length and the length of the UTR.
