Question

Why does splicing represent the dominance of RNA world?

Answer 1

Splicing shows that for conveying message we have to convert dna to rna

SO it shows that due course of evolution the rna since was unstable and reactive were used for protien transfer and dna as storage. But it is assumed that some millions years ago there was only rna present as genetic material as shown by many of viruses today

Answer 2

EXPLANATION:

It is also known for representing the process of dominance regarding respective world of RNA where it implies for deciding to keep intron or not respectively. It also helps for forming the RNA also through respective introns using.  

For conveying the messages for converting the DNA to RNA which is shown by splicing. It also shows the evolution course of RNA due to which the unstable as well as reactive RNA uses the protein for transferring and for strong DNA too.
