Thus at convergent boundaries, continental crust, made of granite, is created, and oceanic crust is destroyed. Two plates sliding past each other forms a transform plate boundary. ... In contrast to convergent and divergent boundaries, no magma is formed.
Just say we have a big amount of tryptophan in the sense that it exceeds, tryptophan would act as a co-repressor which prevents synthesis of more enzymes for its production
Hope this helps :)
The answer would be tissues.
