It is hypothesized that RNA may have evolved before DNA because RNA molecules

were the first molecules synthesized by Miller and Urey
are more important to genetic inheritance than DNA
can catalyze a variety of biologically important reactions
are found in more modern cells than are DNA molecules

It is hypothesized that RNA may have evolved before DNA because RNA can catalyze a variety of biologically important chemical reactions (Option 3 is correct).

What is RNA?

RNA is a special class of nucleic acid that serves as the reservoir of genetic material for certain viruses, which is composed of only one nucleotide chain strand listed of two stands as occur with the double helix of DNA.

In conclusion, it is hypothesized that RNA may have evolved before DNA because RNA can catalyze a variety of biologically important chemical reactions (Option 3 is correct).
