Solution
The correct option is D Genetic code is universal
Order of nucleotides in mRNA determines the amino acid sequence in the polypeptide chain of protein during translation. As genetic code is universal, hence same order of nucleotides will result in the incorporation of same amino acid during translation in various organisms. That is why production of human protein in bacteria by genetic engineering is possible.
So, the correct option is 'Genetic code is universal'.
