Detailed explanation-1: -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.

Detailed explanation-2: -Answer and Explanation: The second step of protein synthesis is translation. Protein synthesis begins in the nucleus where transcription occurs. During transcription, DNA is copied to messenger RNA (mRNA). The mRNA is then exported to the cytoplasm through the nuclear pores.

Detailed explanation-3: -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-4: -Three main types of RNA are involved in protein synthesis. They are messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). rRNA forms ribosomes, which are essential in protein synthesis.
