Question
Which of the following statements about antibodies are FALSE?i. They can recognize antigens based on complementary shapes.ii. They can recognize only non-protein antigens.iii. Activated B cells can produce different classes of antibodies with the same variable region.iv. The H and L chains in an antibody are linked together via intrachain disulfide bonds.ii and iiiii and iviii and ivi and ii
Solution
The false statements about antibodies are:
ii. They can recognize only non-protein antigens. iv. The H and L chains in an antibody are linked together via intrachain disulfide bonds.
So, the correct answer is iii and iv.
Explanation:
ii. Antibodies can recognize both protein and non-protein antigens. They are not limited to recognizing only non-protein antigens.
iv. The H (heavy) and L (light) chains in an antibody are linked together via interchain disulfide bonds, not intrachain disulfide bonds. Intrachain disulfide bonds are present within the chains themselves to maintain their structure.
