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.
Proteins are a diverse group of large, complex molecules that are crucial to every aspect of the body's structure and function. Collagen, which forms the structural scaffolding of skin and many other tissues, is a protein.
