Compared to the MHC molecule on the left, the MHC molecule on the right (in the drawing above) will bind a ______ peptide that, if foreign, will cause a T cell to activate and _________. The protein on the left is made up of two peptides, each with two domains. One peptide has domains labeled alpha 1 and 2, the other beta 1 and 2. The protein on the right is made up of two peptides, one with three domains labeled alpha 1, 2 and 3 and the other a single domain labeled beta MG.
