RNA synthesis

RNA synthesis is the process by which the cell creates messenger RNA (mRNA) from a DNA template. It begins when an enzyme called RNA polymerase binds to a specific DNA region near a gene. The enzyme unzips the DNA strands and reads the genetic code. As it moves along, it assembles a complementary strand of RNA by linking together building blocks called nucleotides. This process copies the genetic information from DNA into a form that can be used to produce proteins. Once completed, the mRNA exits the nucleus to guide protein synthesis in the cell.
