Question

Consider the following statements and select the correct option:
(a) Transcription and translation can be coupled in bacteria
(b) The split gene arrangements represent 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

• A. a, b, d
• B. a, b, c
• C. a, c, d
• D. All of the above

Answer 1

The correct option is D All of the above

A split gene or interrupted gene contains both exons and introns. Exons are the sections of the gene which can be expressed into RNA and proteins.
Transcription and translation can be coupled in bacteria.
The process of splicing represents the dominance of RNA-world.
The presence of introns in split gene is reminiscent of antiquity.
