Elongation of proteins', 'role': 'user'}, {'content': 'Answer: D \nExplanation: tRNA fixed at the p site does not carry any amino acid and is therefore released from the ribosomeThen the whole ribosome moves over mRNA through the distance of one codon. The peptidyl tRNA is translocated to the P Site; this done with the help of elongation factor 2Translocation requires hydrolysis of GTP TO GDPRef: DM Vasudevan, 7th edition, page no: 601, 602', 'role': 'assistant'}]
