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 muscle cells then secreted proteins, primarily collagen, which formed a ring of biosynthetic tissue around the gradually dissolving scaffold, says study researcher Shannon L. M. Dahl, PhD, senior director of scientific operations for Humacyte.
