Loop are the two functional ends of trna
WebAnticodon Loop and Acceptor System The two functional ends of tRNA are which of the following? Splicing The process of alternative _______ can produce different transcripts … WebA model is suggested in which two loops of the 23S RNA, brought into close proximity via folding, are involved both in binding the 3′-ends of the tRNAs and in catalyzing peptide bond formation. This model presumes a dynamic structure for ribosomal RNA, which is modulated by interaction with elongation factors and ribosomal proteins.
