Answer:

All of the experiments listed helped establish that RNA could serve as an informational molecule.

Explanation:

RNA was the first genetic molecule.

Researchs in the 1960s identified messenger RNA to be able to store genetic information, while transfer and ribosomal RNA can translate genetic information into proteins. Research in the past two decades was on the point that some RNAs may function as an enzyme to self-edit its particular genetic code! These findings led to two questions: "1) Why does RNA play so many roles in the flow of genetic information? 2) Why bother storing genetic information in DNA, if RNA alone could do the job?"

RNA posseses strong capability as a genetic moleculeand can transfer hereditary activities on its own. This was the background that RNA was the first molecule of heredity, having all the basic methods for storing and expressing genetic information Before more knowledge on DNA was discovered.
