The correct order for B-cell activation is:
- B cells rearrange their DNA to create a unique B-cell receptor.
- B cells display antigens in MHC class II receptors on the cell surface.
- B cells become activated by interacting with helper T cells.
- B cells undergo clonal expansion.
- B cells digest antigens that bind to the antibodies on their surface.
- Antibodies released by plasma cells bind to antigen so they will be destroyed by other cells of the immune system.
This sequence outlines the series of events that occur during the activation of B cells, starting from the rearrangement of DNA to produce a unique B-cell receptor to the final step of antibodies released by plasma cells binding to antigens for destruction by other immune cells.
