The correct answer is option A, that is, DNA is photocopied to make RNA.
Transcription refers to the procedure by which DNA is transcribed or copied to make mRNA (messenger RNA) that conducts the information required for the formation of protein. Transcription occurs in two broad stages. First is the formation of pre-messenger RNA, with the application of RNA polymerase enzymes.
The pre-messenger RNA is then amended to generate the desired molecule of mRNA in a procedure known as RNA splicing.
