Recent evidence suggests that may have been the first nucleic acid system to form. a) proteins. b) dna. c)rna. d) none of the above

The correct answer is option C- RNA.

Explanation:

RNA World Hypothesis suggested that RNA was the molecule which was utilized by the earliest life on Earth as genetic material and as an enzyme.

The reactions performed by the ribozyme required strands of RNAs which is made up of 30-40 nucleotide which still catalyze the reactions like the process of central dogma and even the single-stranded RNAs in the absence of enzymatic catalysts were able to replicate via template-directed polymerization. This suggests that RNA served as the genetic material prior to DNA.

Thus, option C- RNA is the correct answer.
