Detailed explanation-1: -During transcription, DNA is used as a template to make a molecule of messenger RNA (mRNA). The molecule of mRNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. During translation, the genetic code in mRNA is read and used to make a protein.

Detailed explanation-2: -Summary. 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-3: -Translation is the second step of protein synthesis. Once transcription and the following processing are complete, translation is initiated. This is where the newly created mRNA’s genetic code is read and used to produce protein molecules. Once mRNA leaves the nucleus it travels to a ribosome.
