Answer:
DNA
Explanation:
DNA is a nucleic acid. It is a polymer of deoxyribonucleotides that are bonded together by phosphodiester bond to make long DNA strands. DNA is the most stable biomolecule in the history of life on earth and continues to serve to store the genetic information of living beings. Several species-specific sequences are DNA are conserved during evolution. This makes the DNA the best molecule to store any valuable information.
RNA is comparatively more reactive and prone to mutations due to the presence of ribose sugar and uracil base in it. The structure of a protein is determined by DNA nucleotide sequences. Any change in DNA would also change the structure of a protein.
