The answer is D, B, C. During splicing superfluous information transcribed from the introns of the genes is edited out of the mRNA.

Transcription is the process whereby an mRNA copy of the DNA of the gene is produced before a polypeptide can be synthesised.

Translation comprises production of tRNA by mRNA, with the tRNA amino acids arranged in the order necessary for the production of the specified polypeptide.

Stretches of DNA nearer 3' end of chain are promoters which control transcription by acting as switches upstream to the gene to be transcribed.

Enzyme induced methylation is a post-translation modification of polypeptide in the somatic cell.
