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.
DISTRIBUTED SCAFFOLDING. Scaffolding is an often-used construct to describe the ongoing support provided to a learner by an expert. In this entry, the original notion of scaffolding and its key tenets are discussed, followed by a description of the use of the construct in classrooms and in computer-based systems.he 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).
