Practice question
Question
In an attempt to increase the yield of a commercially important enzyme from natural isolate several strategies were adopted as follows: A. Genome was selectively modified to increase yield. B. Reappraisal of culture requirements of the modified organism to increase yield. C. Induced mutants were screened and selected for organism synthesizing improved levels of the enzyme. D. Organism was genetically modified, so that it produces a factor that enhances stability of the enzyme. Which one of the following options represents strategies that are appropriate for the purpose?
Explanation
Analysis of in an attempt to increase the yield shows A, B, C and D represents established outcome. functional assays supports option A, whereas distractors confuse substrate or regulatory direction and fail to reproduce observed results.
