1. The pre-B-cell receptor provides an important signal that induces transition of pro-B cells to pre-B cells. An important characteristic of this receptor is that: A. It signals without binding to an extracellular ligand. B. It is composed of immunoglobulin heavy chains and the VJ region of a rearranged gamma light chain. C. It is expressed at very high levels on the surface of the pro-B cell. D. It signals without requiring association with B-cell receptor signaling subunits, Igalpha and...
