You are studying a biochemical pathway and isolate mutants I, II, and III.
Mutant I can grow if you supplement the medium with Z.
Mutant II can grow if you supplement the medium with X, Y, or Z.
Mutant III can grow if you supplement the medium with X and Z, but not with Y.
Draw a biochemical pathway showing the correct order of X Y and Z, and the enzymes that each mutant is defective for.
Assume that A is the known starting point of the pathway,
preceding all the molecules and information given above. Order of
the steps in the pathway and step affected by each mutation is as
below-

Wild-type bacteria can grow on minimal medium. Four mutants that cannot grow on minimal medium but can grow on minimal medium supplemented with the nutrient āCā are isolated. It is suspected that metabolites A, B, and D are in the biochemical pathway for synthesis of C, so each mutant is tested for the ability to grow on minimal medium supplemented with these metabolites: Mutant 1: can grow on minimal medium supplemented with A, but not B or D Mutant 2:...
Wild-type bacteria can grow on minimal medium. Four mutants that cannot grow on minimal medium but can grow on minimal medium supplemented with the nutrient "H" are isolated. It is suspected that metabolites T, P, and A are in the biochemical pathway for synthesis of H, so each mutant is tested for the ability to grow on minimal medium supplemented with these metabolites: A. Mutant 1: can grow on minimal medium supplemented with T, but not P or A B....
Imagine you do a version of the Beadle-Tatum experiment in which you attempt to test the one-gene, one-enzyme hypothesis, but using the pathway of synthesis of amino acid Q from X (below). The reactions, in order, are catalyzed by enzymes E1-E5. X is always present in cells, and cells need Q to grow. E1 E2 E3 E4 E5 - xty 2 z 3 photo You identify a mutant strain that doesn't grow in normal medium, but does grow in medium...
45. (2 pts) A. If two mutants complement each other, you would conclude that thes genels, If mutants fail to can co complement, you can conclude that the mutations are in You performed a mutant screen to study color development in beets, and obtained several mutants that are golden in color. You mate these mutant strains for complementation tests and get the following results. (+'indicates wildtype (red), while indicates the mutant phenotype of golden.) m1 m2 m3 m1 m2 m3...
the one I have selected for the first part was wrong. need
help with both parts. Thank you!
Suppose a researcher investigates the pathway of synthesis of compound D. This compound is necessary for growth and survival in many fungi, including Neurospora species. He produces three mutants and places each mutant in each of four different growth supplements. The researcher records the production of compound D in this data table. Minimal medium Supplement A Supplement B Supplement Mutant 1 Mutant...
You are studying the live biosynthetic pathway in bread mold that produces a protein necessary for life. Your research group has identified three genes believed to function in the live pathway and has created mutant lines for each: die-21, die-18, and die-1. You have been growing the mutant strains and a wild-type strain on deficient media that does not contain all four of the compounds involved in the live pathway: A, B, C, and D. To determine the order of...
34. (6 points) Currently you are studying threonine synthesis in yeast. To find genes whose protein products are important for threonine synthesis, you perform a mutagenesis to find mutants that require a source of threonine to grow. You find a total of nine mutants, all of which have recessive phenotypes. You perform complementation tests with all of your mutants. Below are the results for your complementation tests. A (+) means growth and a() means no growth: mtl mt2mt3m4 mt mt...
Made up amino acids Bleucine and Isobleucine are synthesized in a series of steps from made up sugar Blorptose. These are essential for the organism to grow but can be supplied in the medium otherwise to complement the growth defect of mutants when amino acids cannot be synthesized. There are a number of chemical intermediates that are each synthesized by enzymes. Some enzymes in the pathway give both Bleu- and Isobleu- phenotypes, while others are only Bleu- or Isobleu-. You...

Can anyone please help me get this question started. I'm told I may
have a question similar to this on my final and am very confused on
the question. Thanks in advance for any help.
