segment until they are activated.
е.
the conversion of the amino acid phenylalanine into non-harmful tyrosine is mutated and
doesn't work as well (or at all). Phenylalanine will still break down into tyrosine by itself,
ol because this is a favorable reaction. Why is the non-functional enzyme a problem? Explain in a
