DNA directed synthesis of RNA. RNA polymerase.... Protein synthesis in ribosome Protein synthesis in ribosome. transcription and translation. synthesis of mRNA from DNA in the nucleus. The mRNA ...

This process of protein synthesis occurs in two stages - transcription and translation. When a gene is to be expressed, the base sequence of DNA is copied or transcribed into mRNA (messenger RNA).
