The answer is B (speed up chemical reactions).
DNA has to be transcribed into RNA because not only can dna not leave the nuclear for translation at the ribosomes
Also for translation to occur the codons on the mRNA match up with the codons on the tRNA which is connected to the amino acids forming the chain
Universal genetic code means the code is responsible for synthesis of the same protein in every organism.
