A - C gene for gamma and C gene for alpha
ok i just looked at the notes. thank u. yes i remember now.lolz dr. seetal no need to worry dude i shall xplain u
The correct answer is A. The genes for the synthesis of the entire heavy chain are present on human chromosome 14. Of the options given above, the only genes that are present on one chromosome are for the
C (constant) regions of the heavy chains. Remember, the heavy chains determine the identity of the immunoglobulin isotypes: IgG, IgM, IgA, IgD, and IgE.
Choice B: The C gene for the gamma heavy chain is on chromosome 14 and the C gene for the kappa light chain gene is on chromosome 2.
Choice C: The V gene for the kappa light chain gene is on chromosome 2. The C gene for the epsilon heavy chain is on chromosome 14.
Choice D: The V gene for the lambda light chain gene is on chromosome 22. The C gene for the kappa light chain gene is on chromosome 2.
Choice E: The V gene for the lambda light chain gene is on chromosome 22 and the V gene for the heavey chain gene is on chromosome 14.
