I have the following fastqc profile and i´m just trying to understand what´s wrong with blue line. This is a human microRNA rna seq experiment (1x50bp) from human blood extracted microRNAs.
In adapter content it starts around 18 (y axis) (small RNA 3´adapter). Why is that ?? Too much adapter ??
In the GC content i have a pick at 50%. Is that primer dimer or any type of contamination??
