Conserved Noncoding Elements (CNEs) are elements exhibiting extreme noncoding conservation in Metazoan genomes. They cluster around developmental genes and act as long-range enhancers. yet nothing that we know about their function explains the observed conservation levels. Clusters of CNEs coincide with topologically associating domains (TADs). https://www.roneverhart.com/Seagate-Exos-7E2-ST1000NM0008-1TB-7-2K-RPM-SATA-6Gb-s-512n-128MB-3-5-Hard-Drive/
