Choose the statement(s) about the RNA world hypothesis which is/are true. There may be more than one correct statement According to this hypothesis, RNA genomes will in the future, replace DNA genomes RNase P provides evidence that RNA can function as a catalyst. Ribosomes provide evidence that RNA can function as a catalyst. According to this hypothesis, RNA genomes would need to self-duplicate. According to this hypothesis, RNA evolved after DNA to allow transfer of information from DNA to proteins.

Explanation / Answer

Ribosomes provide evidence that RNA can function as a catalyst.

According to this hypothesis, RNA genome would need to self duplicate.
