What is transcription in biology?


Quick Answer

Transcription is the biological process where information in a strand of DNA is copied into a new molecule of messenger RNA. This transcribed DNA message or RNA transcript produces proteins.

Full Answer

There are three stages that make up DNA transcription. First, DNA is transcribed by an enzyme called RNA polymerase. Then, transcription factors elongate the DNA strand and allow RNA polymerase to transcribe only a strand of DNA into a RNA polymer called messenger RNA. Finally, RNA polymerase continues along the DNA until it reaches what is called a terminator sequence. When that point is reached, the RNA polymerase releases the mRNA polymer and detaches from the DNA.
