Why does DNA need RNA? DNA is a precious commodity and to prevent it from damage it should not involve in many process. On the other hand it contains the genetic code for production of protein â¦
In biology, scaffold proteins are crucial regulators of many key signaling pathways. Although scaffolds are not strictly defined in function, they are known to interact and/or bind with multiple members of a signaling pathway, tethering them into complexes.
Scaffolding in general means a structure providing support. The best example of scaffolding in biology is the repair of a broken bone (fracture). An initial temporary structure is made by the body called the pro callus. On this further growth takes place. And it undergoes intensive remodeling.
