Comments P.182 left column 2nd paragraph: "The vast majority of our genes has a puzzle-like structure where short coding sequences (exons) must be correctly identified and joined together while surrounding much longer non-coding sequences (introns) have to be removed before a mature mRNA is exported to the cytoplasm and translated. A typical human gene contains 8 introns of average length ~3.4 kb but much larger examples were found (e.g., the last intron of glypican 5 gene is 721 kb in length)(primary source)." Precise value in primary source is 3.365kb. Median number of exons in primary source is 7 exons, i.e 8 introns
