    I was revising biotechnology and I came across a difficult question that my teacher asked me. How could you test for the lactase enzyme that has been lost in a solution of milk? I thought that using the biuret test (the test for protein) would work but realised milk has its own proteins. I know its a silly question but I have been stressing about it.

    Thank you.
Do you agree with the PM's proposal to cut tuition fees for some courses?
