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 cytoskeleton is the scaffolding of a cell. It is composed of microtubules, actin filaments, spectrin tetramers, and intermediate filaments.he cytoskeleton contains microtubules, actin micofilaments, and intermediate filaments. These collectively play a role in giving shape to cells, allowing for cell movement, m â¦ ovement of organelles within the cell and endocytosis, and cell division. 3 people found this useful.
