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 notion of scaffolding is increasingly being used to describe the support provided for students to learn successfully in classrooms, especially the use of project-or design-based activities to teach math and science (e.g., Kafai, 1994; Kolodner et al., 2003; Krajcik et al., 1998).
