Solution
The correct option is B Bacteria
Introduction to cistron
1) Cistron is a region of a DNA that codes for a specific polypeptide.
2) In prokaryotic cells such as bacteria, it only consists of exons (coding segments).
3) In eukaryotic cells it is made up of both exons and introns (non-coding segments).
1) The spliceosome is a ribonucleoprotein complex made up of small nuclear RNA (snRNA) and proteins.
2) It helps is splicing off introns from the primary RNA transcript during post-transcriptional processing in eukaryotic cells such as those in animals, plants and fungi.
3) Prokaryotes, such as bacteria, do not possess introns and hence do not require spliceosome for splicing introns during post transcriptional processing of primary RNA transcript.
Final answer
(C) Bacteria
