Correct answer: D

Introns, which occur principally in eukaryotes, are transcribed into messenger RNA (mRNA) but are subsequently removed from the transcription before translation. In certain cases, removal of the introns is an autocatalytic process (selfsplicing) whereby the RNA itself has the properties of an enzyme.
