Why are nucleic acids carriers of genetic information?

Nucleic acids are the basic building blocks of DNA and RNA. With the help of them, genetic information is encoded. Nucleic acids have this property. How exactly they appeared and how they formed the DNA chain is still unknown. Scientists put forward many theories. But it takes time and resources for research to confirm or disprove a theory. Much is not clear in the very structure of DNA. But scientists have not only “decoded” DNA, but can rearrange the genes of a certain organism with another.
