Explain how auxotrophic mutants can be isolated and how they inform us about metabolic pathways CORRECT ANSWER - screen for mutations in prototrophs (an organism capable of synthesizing all its metabolites from inorganic material) that cause them to become auxotrophic for a certain metabolite - map the mutation to a particular enzyme, then match enzyme to metabolic pathway - accumulations of the intermediate made before the blocked pathway help us piece together the biosynthetic pathways p...

Anticodon - A specialized base triplet at one end of a tRNA molecule that recognizes a particular complementary codon on an mRNA molecule.
