Short pre-mRNAs are prone to leak from the nucleus. (A) Boxplots of the transcript length of human RefGenes, nuclear retained pre-mRNAs, and leaked pre-mRNAs. (B) Boxplots of the intron length of human RefGenes, nuclear retained pre-mRNAs, and leaked pre-mRNAs. (C) Boxplots of the exon number of human RefGenes, nuclear retained pre-mRNAs, and leaked pre-mRNAs. (D) Boxplots of the RPKM of human RefGenes, nuclear retained pre-mRNAs, and leaked pre-mRNAs.
