Explanation:
Detailed explanation-1: -The first step of protein synthesis is transcription-the unfolding of DNA and the production of a messenger-RNA (mRNA) strand. In the second step of protein synthesis-translation-tRNA and mRNA interact to code amino acids into growing polypeptide chains.
Detailed explanation-2: -Cell uses the genes to synthesize proteins. This is a two-step process. The first step is transcription in which the sequence of one gene is replicated in an RNA molecule. The second step is translation in which the RNA molecule serves as a code for the formation of an amino-acid chain (a polypeptide).
