Consider the following four statements (a-d) and select the option which includes all the correct ones only.
(a) Transcription and translation can be coupled in bacteria.
(b) The split gene arrangement probably represents the advanced feature of the genome.
(c) The process of splicing represents the dominance of RNA-world.
(d) The presence of introns in split gene is reminiscent of antiquity.

The split-gene arrangements represent probably an ancient feature of the genome.

The presence of introns is reminiscent of antiquity.

The process of splicing represents the dominance of RNA-world.

In bacteria, many times the translation can begin much before the mRNA is fully transcribed as both the processes occur in the same compartment as there is no separation of cytosol and nucleus in bacteria. Hence, transcription and translation can be coupled in bacteria.
