The heavy and light chains of the antibodies are linked to one another

1.	The heavy and light chains of the antibodies are linked to one another by ____________________(a) covalent bonds(b) disulfide bonds(c) ionic bonds(d) hydrogen bondsThe question was posed to me in an interview for internship.My enquiry is from Immune Response in chapter Immune Response of Cell Biology
Answer» Correct option is (b) DISULFIDE bonds For explanation I would say: The ANTIBODIES are globular proteins that CONTAIN heavy CHAINS (molecular mass of 50,000 to 70,000 daltons) and LIGHT chains (23,000 daltons). The heavy and light chains are joined together by disulfide bonds.
