Out of the following given choices;


A. O-linked; serine


B. O-linked; asparagine


C. O-linked; threonine


D. N-linked; glutamine


E. N-linked; asparagine


The answer is B. O-Linked referred to type of glycosylation of the proteins. This type of glycosylation involves attachment of a monosaccharide or an oligosaccharide molecule to an oxygen atom in an amino acid residue of proteins. While N-linked glycosylation is an attachment of an oligosaccharide molecule to an amide nitrogen atom of arginine or asparagine of proteins. Glycosylation (a post-transcriptional modification) is a bond formed from donor of a glycosyl group (usually a carbohydrate ) and a glycosyl acceptor. This occurs in the constant domains of antibodies such as IgG.
