Co-Evolution of Transcriptional Silencing Proteins and the DNA Elements Specifying Their Assembly

Co-Evolution of Transcriptional Silencing Proteins and the DNA Elements Specifying Their Assembly: "

As shown by genetic assays in Saccharomyces interspecies hybrids, the co-evolution of heterochromatin assembly proteins with silencer elements allows transcriptional silencing functions to be maintained in rapidly evolving regions of the genome.
