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 the zone of proximal development. Scaffolding is another fundamental concept of the ZPD theory. The term scaffolding was introduced by Wood, Bruner. and Ross (2001) in an attempt to operationalize the concept of teaching in the ZPD (Wells, 2000).
