And that's because we want to actually prevent damage to the DNA molecules. And so what we do is in a process known as transcription we synthesize RNA molecules from DNA molecules. And what these RNA molecules are they're copies of specific segments of the DNA molecule and these segments usually contain important genes. So before we can synthesize proteins RNA molecules must be synthesized from DNA molecules in a process known as transcription. And just like the process of DNA replication involves this protein known as DNA polymerase that catalyzes the formation of a phosphodiastor bond in the process of transcription. When we form the RNA from the DNA there is a molecule, a protein known as RNA polymerase that catalyzes the formation of the phosphodia Esther Bond.
