Question

T/F: during rearrangement of alpha:beta TCRs, expression of functional pre-TCR results in deletion of all delta gene segments

Answer 1

During the rearrangement of alpha:beta TCRs, the expression of functional pre-TCR does not result in the deletion of all delta gene segments.

Step-by-step explanation:

During the rearrangement of alpha:beta TCRs, the expression of functional pre-TCR does not result in the deletion of all delta gene segments. The rearrangement process involves the combination of different gene segments to code for the variable regions of the TCR. The alpha:beta TCR rearrangement can result in the deletion of specific gene segments, but it does not delete all delta gene segments.
