Overview of Protein Synthesis Genes are instructions for making proteins. In eukaryotic cells, protein synthesis occurs in three steps. First, an RNA molecule is assembled along a DNA template. This step is called transcription. In the second step called RNA processing, the ends of the RNA transcript are altered, some portions of the RNA molecule are deleted, and the remaining portions are spliced together to make messenger RNA. The mRNA synthesized then leaves the nucleus and attaches to a ribosome and initiates the process called translation. During translation, the ribosome then reads the RNA message and links amino acids together to form a polypeptide.
