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.
The ECM acts as a sort of scaffold, holding the cells in place (like jelly beans embedded in jello, or bricks held together by mortar). Cells attach themselves to this protein scaffold by yet more adhesion proteins.
