REVIEWED JOURNAL ARTICAL ON THE TOPIC OF DIRECTED EVOLUTION AND WHAT IT HAS TO DO WITH LACTOSE INTOLERANCE.

The article you review should come from PUBMED. 

You should discuss what directed evolution is, what it is used for , different types of mutagenic techniques ( chemical mutagenesis) , PCR (recombinant PCR, Error Prone PCR), different types of selections (metabolic selections), X- gal. Discuss when the added enzyme works (only during flash pasterization) due to its temperature range. 

For better understanding, I am researching how can people who are lactose intolerant still enjoy dairy products.
