Genetic Code and Codon Arrangement — NEET Biology
📚 Practice ConceptIf we insert a letter B in between HAS and RED and rearrange the statement, it would read as follows:
Which of the following statements are correct regarding the termination phase of protein synthesis? S1. Termination of translation occurs when a stop codon is encountered in the A-site of the ribosome. S2. Stop codons (UAA, UAG, UGA) are recognized by specific tRNAs that carry no amino acid. S3. Release factors bind to the stop codon, promoting the hydrolysis of the bond between the polypeptide and the tRNA in the P-site. S4. In the absence of functional release factors, the ribosome would dissociate prematurely from the mRNA. S5. The initiator tRNA is recycled and used again for subsequent rounds of initiation after termination.
