Since a protein has no information content is a ded end. Even if you
would accidentally synthesize a functioning protein this could not
propagate, wheras nucleic acids can copy their sequence via nucleotide
pairing. Also, functional proteins contain from roughly a hundred amino
acids and up, a ribozyme (see spelling) manages with some 20 nucleotides.
