St. Thomas, St. John, and St. Croix-the three islands known to many as the U.S. Virgin Islands, and the reason millions of travelers head to the Caribbean every year.
This copying process is called transcription and the copy is mRNA. Transcription takes place in the cytoplasm (prokaryote) or in the nucleus (eukaryote). The transcription is performed by an enzyme called RNA polymerase. To make mRNA, RNA polymerase: 1  Binds to the DNA strand at a specific sequence of the gene called a promoter. 2  Unwinds and unlinks the two strands of DNA. 3  Uses one of the DNA strands as a guide or template.
On the actual code strand, a strand of messenger RNA (mRNA) is made in a step called transcription. The mRNA then moves to where the actual protein will be made (ribosomes, cell structures which themselves have RNA in their construction), and a small type of RNA performs most of the next step, translation.
