Composition of spermatozoal RNAs. The distribution of the various classes of RNAs as determined by RNA-seq is shown. The most abundant class is ribosomal RNAs followed by mitochondrial RNA (mitoRNAs), annotated coding transcripts, small non-coding RNAs (snc-RNAs), intronic retained elements, lnc-RNAs and Transcribed regions of Unknown Coding Potential (TUCP), short expressed regions, transposable elements and annotated non-coding RNAs, including snars, sno, pri-mir and RNU.
