What is the importance of DNA packaging DNA packaging is important because the DNA is very long. Biomolecules can be loaded onto the surface of DNA-scaffolded particles using one of two strategies: (1) through a surface step-by-step conjugation via a bifunctional linker and (2) through. The chromatin is further folded to form different structures that eventually form chromosomes. These keywords were added by machine and not by the authors. The cells wrap their DNA around scaffolding proteins to form a condensed structure called chromatin. The organization of signaling complexes on scaffold proteins is dynamic, and there is an order of assembly that may vary. The chromosome scaffold, prepared by dehistonization of chromosomes with 2 M NaCl, is a nonhistone protein complex to which many looped DNA molecules are. Thus, there is a cellular need to organize pathways both in time and space, a role that is achieved by scaffold proteins. These molecules need to be organized into complexes that will affect timing, location, and even specificity and magnitude of a single response, such as to growth factors or protection against DNA damage, for example. Thus, pathway components need to be partially preorganized so that signal transduction is not limited by the diffusion kinetics of individual molecules. An individual cell has over one billion proteins, of which ten percent form part of signaling pathways and networks, and none of them is exclusive for a single pathway. ![]()
