Transcription of a typical gene encoding a polypeptide in eukaryotes involves all of the following EXCEPT: A) the splicing together of a number of exons in the DNA prior to transcription. B) synthesis by RNA polymerase II. C) transcription of DNA corresponding to both introns and exons. D) transcription of the DNA which encodes the N-terminal of the polypeptide prior to DNA encoding to the C-terminal. E) addition of the poly(A)⁺ tail.
