Bacteria Morphology The cell walls of Gram positive bacteria contain two modified sugar, viz. N- acetylgucosamine (NAG) and N- acetylmuramic acid (NAM). They are covalently linked by β-1,6-glycosidic bond α- 1,6-glycosidic bond α- 1,4-glycosidic bond β- 1,4-glycosidic bond β-1,6-glycosidic bond α- 1,6-glycosidic bond α- 1,4-glycosidic bond β- 1,4-glycosidic bond ANSWER DOWNLOAD EXAMIANS APP
