This modification further protects the pre-mRNA from degradation and signals the export of the cellular factors that the transcript needs to the cytoplasm.

It covers their structure, role in catalysis, and historical significance, emphasizing the RNA world hypothesis where RNA preceded proteins. The section examines examples like self-splicing introns, RNase P, and the ribosome as ribozymes, explaining their mechanisms and significance in evolution and cellular regulation.

It explains RNA processing's role in transforming pre-mRNA into mature mRNA, promoting mRNA stability, nuclear export, and translation initiation. RNA splicing involves removing introns and linking exons with spliceosome assistance, while polyadenylation entails adding a poly-A tail for mRNA stability.
