Deciphering transcription regulation: from individual sites to cell type specific expression

Published on Oct 23, 20122846 Views

Understanding how transcription regulation is encoded in the genomes of complex multicellular organisms has been a big challenge, not least due to the large non-coding space where relevant interac
