“…The double helical structure provided a hint as to how DNA could be self-replicating and genetic information stored and read [3]. The next discoveries of mRNA by Sidney Brenner, Francois Jacob, and James Watson; mechanisms in the protein synthesis by Francois Jacob, and Jacques Monod; the genetic code first letter phenylalanine encoded by poly(U) by Heinrich Matthaei and Marshall Nirenberg; the ribosomes the synthetically active, membrane-free particles by George Palade and Howard M. Dintzis [4]; the nucleosome, basic structure of DNA-protein complex in eukaryotes by Ada and Donald Olins [5] and many others opened a new era in science. Fitting nucleosomal strings into a small space in the cell nucleus, the implementation and copying of genetic information requires higher-order structures of the nucleosome chains and the possibility of their fast changes if needed.…”
