Assertion (A): The process of translation or protein synthesis 'terminates when the A-site of ribosome encounters a termination codon. Reason (R): A release factor liinds to the stop codon and translation is terminated.

Assertion : in recombinant DNA technology, human genes are often transferred into bacteria (prokaryotes) or yeast (eukaryote). Reason: Both bacteria and yeast multiply very fast to form huge population which express the desired gene.
