Function of RNA Polymerase in Transcription

In molecular biology, the central dogma describes the flow of genetic information within a biological system. It primarily involves processes such as transcription and translation. In transcription, the DNA sequence of a gene is copied into messenger RNA (mRNA). This mRNA then travels out of the nucleus into the cytoplasm, where it serves as a template for protein synthesis during translation. One important aspect of transcription is the role of RNA polymerase, which binds to the DNA at a specific region and synthesizes the mRNA strand.
