Answer:
The proper order is as follows-
1) A B cell differentiates from a lymphocyte stem cell, and the mature B cell expresses a specific type of B cell receptor on its cell membrane.
2) Gene expression is altered in the B cell, and the B cell begins to divide.
3) Several rounds of division occur, producing many B cells that all express the same B cell receptor.
4) The B cell's BCR (B cell receptor) binds to a foreign antigen with high specificity and high affinity.
5) Second messenger signaling is activated in the B cell.
