When an immature T-cell fails to productively rearrange its genes, which of the following happens?

A T-cell going through the selection process can:

Formation of the pre-TCR induces proliferation of thymocytes, during which the expression of RAG1 and RAG2 is maintained.

Which chemotactic molecule signals naive T-cells that do not meet their antigen in a lymph node to exit that lymph node and continue to recirculate until they do meet their antigen?

In a timeline of a T-cells life, a double negative thymocyte would come __________ becoming a CD4 T cell.

Which of the following is true about S1P?

You would expect to see Notch-1 being expressed in the thymus during T-cell maturation.
