Transcription is a biological process that copies a segment of DNA into RNA. The enzyme RNA polymerase carries out this synthesis. The newly synthesized RNA molecule then leaves the nucleus and enters the cytoplasm, where it is translated into protein. 

Transcription can be broken down into three steps: initiation, elongation, and termination. 
Transcription can also refer to the process of converting speech or audio into a written document. For example, writing down a voicemail message or rewriting class notes are examples of transcription.
