Question

Production of human protein in bacteria by genetic engineering is possible because

• A. Human chromosome replicate in bacterial cell
• B. Mechanism of gene regulation is identical in humans and bacteria
• C. Bacterial cell can undertake RNA splicing
• D. Genetic code is universal

Answer 1

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'.
