1. How is the heavy chain rearrangement different from the light chain rearrangement?
Heavy chain gene rearrangement can occur simultaneously on loci and multiple attempts can be made if the first two fail.
Light chain gene rearrangement can occur simultaneously on loci and multiple attempts can be made if the first two fail.
Heavy chain gene rearrangement occurs on one loci at a time, but multiple attempts can be made on each gene.
Light chain gene rearrangement occurs on one at a time, but multiple attempts can be made on each gene.
Light chain and heavy chain gene rearrangement occurs simultaneiously, with multiple attempts on each gene.
2. Select the B cell that best matches the statement.
A- pre B cell, B- pro B cell, C- Immature B cell, D- B 1 cell
Stage where selection occurs.
Stage where light chain rearrangment occurs
Stage where heavy chain rearrangment occurs
Stage where the protein check point product is a pre-BCR
Stage where the protein check point product is a functional BCR
Stage found in the blood stream
3. A tingible body is:
