Answer and Explanation:
There are three basic steps as initiation, extension and termination which occur in both eukaryotes and prokaryotes. For transcription of a gene to occur, the DNA double helix unwinds over a short region.
initiation: RNA polymerase enzyme is linked to specific portions called as promoter in DNA to start RNA synthesis after the DNA unwinds.
Elongation: the enzyme synthesizes RNA strand along the DNA chain.
Termination: RNA synthesis continues along the DNA strand until it encounters a signal representing termination of the process. The termination process happens as the transcription complex separation takes place on the DNA sequence.
When assembled in the nucleus,mRNA peels off and moves to the cytoplasm. Here, it attaches to the ribosomes.Protein synthesis is started with AUG codon which is at the beginning of the mRNA-carried code. As the mRNA moves along the ribosome its information is translated into the appropriate amino acids which are assembled into a polypeptide. this is called translaton.
