Vedclass · Answer

(B) Splicing is the process of removing introns and joining exons in pre-$mRNA$. This process is catalyzed by small nuclear ribonucleoproteins $(snRNPs)$,which are complexes of $RNA$ and proteins. The fact that $RNA$ acts as a catalyst (ribozyme) in this essential biological process is considered strong evidence for the '$RNA$ world' hypothesis. This hypothesis suggests that $RNA$ was the first genetic material and performed both catalytic and informational functions before the evolution of $DNA$ and proteins.

Splicing represents the dominance of which world?
