The case of Lactose Intolerance

After watching the video “The evolution of Lacotse Intolerance” https://www.youtube.com/watch?v=MA9boI1qTuk

Research how a single mutation can change the activity of an enzyme.

Then connect your findings to lactase:

-How does the lactase enzyme normally function in the small intestine.

-What changes in people who are lactose intolerant

-How does a regulatory mutationnot a change in the enzyme itselfaffect lactase production

-Include one realworld example of another enzyme affected by gene regulation.
