Termination is caused by all EXCEPT:: (A) 48 S complex, (B) UAA, (C) RF-1, (D) Peptidyl transferase
Answer is A. 48 s ribosome complex is involved in initiation of translation, not termination. Termination of translation, Stop codons are UAA, UAG & UGA, which do not code for any amino acid. Peptidyl transferase is responsible for the release of polypeptide chain from the P-site of ribosome.
