Transcription involves the process of taking the store genetic information in the DNA, and transferring that information into RNA, or more specifically, mRNA and takes place in the cell’s nucleus. To begin this process, RNA polymerase will start at the beginning of the gene and begin to pull apart the DNA strands. As the RNA polymerase unzips the DNA strands, a complementary strand of mRNA is synthesized to each of the parted strands of DNA. Now that these complementary strands of mRNA are sharing similar base pairs with the opposite strand, DNA, the RNA polymerase will continue to unzip the DNA strands until a signal of the end of the nitrogenous sequencing has occurred and the mRNA, with the duplicated genetic information received from the DNA, will move out of the cell’s nucleus and into the cytoplasm.
