[{'content': "Post transcriptional modification include all except: \nSelect and explain. \nA. 5' capping, B. 3' polyadenylation, C. Splicing, D. Glycosylation", 'role': 'user'}, {'content': "Answer: D \nExplanation: Glycosylation is a post translational modification, not a post transcriptional modification. Post Translational Modifications Post Transcriptional Modifications Phosphorylation Capping at 5'end Glycosylation (most frequent) Removal of Introns/ Splicing Hydroxylation Tailing at 3'end Acetylation Vit K Dependent Carboxylation of Glutamate Biotin covalently bound to Carboxylases", 'role': 'assistant'}]
