For $\alpha$ $\beta$ T-Cell Receptors, Sequence Diversity Is Heavily Concentrated at the Junctions

question 27

Multiple Choice

For $\alpha$ : $\beta$ T-cell receptors, sequence diversity is heavily concentrated at the junctions formed by the rearrangement of gene segments during the generation of the expressed V $\alpha$ and V $\beta$ regions. The result of this organization is to position the most variable part of the T-cell receptor over a certain region of the ligand recognized by this receptor. Which region (outlined in red in Figure ) indicates this part of the ligand recognized by the T-cell receptor?
