From: False gene and chromosome losses in genome assemblies caused by GC content variation and repeats
Biased distribution of sequencing errors near GC-rich 5′-proximal regions of protein-coding genes. a–d Average GC content (red) and frequency of false SNPs or false indels (blue) found in the exons and introns of protein-coding genes (5′: 5′UTR, F: First coding, I: Internal coding, L: last coding, 3′: 3′UTR exon or intron). Left and right panels indicate the upstream and downstream 3 kbp sequences of genes in 100-bp consecutive blocks
