Describe the process of transcription in the cell.
Transcription involves the synthesis of proteins directly from DNA.
Transcription occurs in the cytoplasm of the cell.
Transcription is the process of creating an RNA copy of a segment of DNA.
Transcription is the process of creating a DNA copy of a segment of RNA.
