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...

Brock Biology of Microorganisms - Chapter 11 Exam Study Guide. Mutation - answerheritable change in DNA sequence that can lead to a change in phenotype (observable properties of an organism) wild-type strain - answer-typically refers to strain isolated from nature -this adjective for a strain can also refer to just one gene mutant - answer-a cell of virus derived from wild type that carries a nucleotide sequence (genotype) change -observable properties (phenotype) may also be altered -c...
