The RNA molecule that is produced as a result of transcription is called messenger RNA or mRNA. It carries its 'message' to units called ribosome which will decode the RNA to produce amino acids, which are chained together to build proteins. By Anne Marie Helmenstine, Ph.D.
During transcription, a strand of mRNA is formed that is complementary to the sequence within the DNA. Transcription begins when RNA polymerase binds to the DNA promoter for a gene. The DNA helix is unwound and the primary mRNA strand is made by RNA polymerase.
