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.
This is because the scaffold must mimic the extracellular matrix (ECM) of the body. The ECM is a network of connective tissue that supports and anchors body cells, similar to the role of scaffolds. Like the ECM, scaffolds serve primarily as structural support, providing the shape and rigidity of the physical tissue.
