During the process of gene expression, the DNA to RNA step is known as transcription while the RNA to protein step is known as translation.
Gene expression is a process which involves the synthesis of a functional gene product by using the information present in the genes.
Transcription is a process which involves the synthesis of a RNA from the DNA. In eukaryotic cells, the transcription occurs in the nucleus whereas in prokaryotes the transcription occurs in the cytoplasm of the cell.
Translation is the process by which the RNA is converted into a protein. The translation in prokaryotic cells occurs in the cytosol of the cell whereas in eukaryotic cells, the translation occurs in the ribosomes.
