Title: The following table presents the effect of different media on the growth respons Post by: colleen on Sep 14, 2013 The following table presents the effect of different media on the growth response of tryptophan mutations in Salmonella typhimurium (+ = growth, - = no growth).
Medium Supplemented with Strain No Supplement IGP AA IN TRY trp-8 - + + + + trp-2 - + - + + trp-3 - - - + + trp-1 - - - - + (a) Construct the biochemical pathway for the compounds IGP, AA, IN, and TRY based on these data. (b) Place strains of bacteria (mutations) in the appropriate steps in the pathway. (c) In bacteria, it is often possible to make partial diploid strains. Assume that a diploid strain was made containing the complete genomes of the trp-2 and trp-1 strains. Would this diploid strain be able to grow on the unsupplemented medium? Explain your answer.
