Transcription Transcription- synthesis of RNA from only one strand of a double stranded DNA helix

Transcription Transcription- synthesis of RNA from only one strand of a double stranded DNA helix DNA ???? RNA( ???? Protein) Why is RNA an intermediate???? Protect the DNA; limited access; Gives regulatory opportunity (all cells have the same DNA but not the same genes are expressed)
