Signaling in the living systems : gene keys and gene locks

This article briefly discusses the complex and intricate mechanisms of functioning signaling systems between plasma membrane nucleus in living organisms. An alternative model DNA packaging is described. The milestone this assumption that winds not around histone octamer: it organized two layers nucleosomes. basic structure chromosomes a triplet A single nucleosome parallelepiped shape (11x11x6 nm). to protein receptors proposed composed from nucleic acid (DNA, RNA), called gene keys, open code (gene lock) gene/cluster at promoter.
