Answer: Separation, purification and formulation of the product.
- A Inserting the gene into the vector
- B Separation, purification and formulation of the product
- C Cutting the DNA with specific restriction enzymes
- D Amplifying the gene by PCR
Correct answer: B. Separation, purification and formulation of the product
Explanation: Downstream processing includes separation and purification of the product followed by formulation with preservatives and quality control testing before it is marketed.
Recombinant DNA technology: a gene of interest and plasmid are cut by the same restriction enzyme, ligated into a recombinant plasmid, and introduced into a host cell.
