Organizing and summarizing search results for youTranscription is the process of making an RNA copy of a gene sequence. During transcription, enzymes called RNA polymerases build RNA molecules that are complementary to a portion of one strand of the DNA double helix. RNA polymerases link nucleotides to form an RNA strand using a DNA strand as a template. Transcription has three stages: initiation, elongation, and termination. The RNA copy, called a messenger RNA (mRNA) molecule, leaves the cell nucleus and enters the cytoplasm, where it directs the synthesis of the protein, which it encodes.5 Sources
