Histones, as part of nucleosomes, are responsible for DNA packaging in chromosomes. They also affect DNA expression by a multitude of post-translational modifications, especially prevalent on the amino terminus of histones. Co-activator protein complexes “write”, “read”, or “erase” histone modifications, and in balance determine which sections of DNA are free...
The fact that measuring a quantum system reduces it to apparently classical behavior, eliminating the interference patterns that are a hallmark of quantumness, cries out for an explanation. That explanation has been provided by the recognition of decoherence,whereby the interference is destroyed by the very interaction that acquires information.We begin...
