Ridge (biology)

Ridges (regions of increased gene expression) are domains of the genome with a high gene expression; the opposite of ridges are antiridges. The term was first used by Caron et al. in 2001. Characteristics of ridges are:Gene denseContain many C and G nucleobasesGenes have short intronshigh SINE repeat densitylow LINE repeat density↑ 1.0 1.1
