Promoters and enhancers: Tool catches gene-controlling DNA sequences doing each other's jobs

Researchers at the Weill Institute for Cell and Molecular Biology have uncovered new evidence that two major types of gene-controlling DNA sequences, promoters and enhancers, operate with a shared logic and often perform the same jobs. The finding, made possible through a high-throughput assay they developed called QUASARR-seq, could reshape how scientists design gene therapies, interpret disease-related mutations, and understand cancer genetics.
