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: -First, transcription transfers the genetic information from DNA to mRNA via initiation, elongation, and termination. Following this, the newly created strand of mRNA leaves the nucleus and attaches to a ribosome within the cytoplasm. This is where translation initiates.
Detailed explanation-3: -In eukaryotes, the first step (transcription) occurs in the nucleus. When the transcript (mRNA) is formed, it proceeds to the cytoplasm where ribosomes are located. Here, the mRNA is translated into an amino acid chain.
Detailed explanation-4: -Transcription takes place in three steps: initiation, elongation, and termination.
