Proteins carry out much of the biochemistry of life,including DNA replication,but DNA stores the information needed to build correct proteins.Early life forms would have needed both proteins and DNA,but neither can exist without the other.The RNA world hypothesis is an appealing solution to this problem,because it states that ________.
A) RNA can evolve into DNA by natural selection B) proteins can store the information needed for their own synthesis C) RNA is more chemically stable than DNA D) nucleotides of RNA are chemically similar to amino acids E) some RNA molecules both store information and catalyze chemical reactions
