[{'content': 'Pseudouridine found in? \nSelect and explain. \nA. DNA, B. rRNA, C. mRNA, D. tRNA', 'role': 'user'}, {'content': "Answer: D \nExplanation: Ans. is 'd' i.e., tRNA Modified bases found in tRNA are - Dihydrouridine (D) in which one of the double bonds of the base is reduced. Ribothymidine (T) in which methyl group is added to uracil to form thymine. Thus, tRNA is the only RNA that can contain thymine though only some times. Pseudouridine (yr) in which uracil is attached to ribose by a carbon-carbon bond rather than a nitrogen bond.", 'role': 'assistant'}]
