Human genome - From pieces to patterns

Abstract

A profile of exon-intron lengths in genes shows a normal distribution. This observation suggests that different genes may have portions of their total exon and/or intron lengths in common. In order to explore the common exon-intron structural patterns that may arise due to common lengths across genes, we compared the exon-intron length patterns of annotated human genes. We discovered 1762278 conserved arrangements of exon-intron length across the otherwise unrelated and diverse genomic landscape. The existence of common exon-intron length patterns across unrelated genes suggests for their role of in gene assemblage and human genome design and architecture.
