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.
Transcription. RNA is copied from DNA in a process called. transcription. . During Transcription. The enzyme RNA polymerase binds to DNA and separates the 2 DNA strands. RNA polymerase builds a strand of RNA using one strand of DNA as the template.The DNA is transcribed into RNA following base-pairing rules except that uracil binds to adenine.he enzyme RNA polymerase binds to DNA and separates the 2 DNA strands.
