Under cellular conditions, dATP can be oxidized to its 2-hydroxy form, which is a substrate for an enzyme that converts 2-OH-dATP to 2-OH-dAMP + PPi. Explain why compounds that inhibit the activity of this enzyme would be eff ective anticancer agents.
b. Neurospora has an arginine amino acid synthesis pathway shown below: ornithine citrulline arginine NH H2N H2N OH H2N HO HO NH2 NH2 ÑH2 Enzyme A Enzyme B Enzyme C ↑ ↑ Gene A Gene B Gene C Suppose I have a neurospora strain that has a mutation such that it will not grow unless I supplement the media (food) with arginine (but not with citrulline or ornithine). What gene is mutated? Explain your reasoning. C. Suppose I take the strain above that only grows with arginine supplements and cross it to a different mutant Neurospora strain that grows with arginine and citrulline supplements but not ornithine supplements. Assming genes A, B and C are unlinked and there is only one mutation per strain: i) What percentage of the progeny will grow on ornithine? ii) What percentage on citrulline? iii) What percentage on arginine? Show your work for i), ii) and iii). |
Azathioprine is an immunosuppressant drug used in kidney transplants. In vivo, azathioprine is metabolized to the hypoxanthine analog 6- mercaptopurine, which is then converted into 6-mercaptopurine ribose monophosphate, the active form of the drug. 6- Mercaptopurine ribose monophosphate also inhibits de novo purine synthesis, reducing uric acid levels in the blood and urine. However, when administered to Lesch – Nyhan patients, there was no effect on uric acid levels. Explain why this is the case.

A unique aquatic plant was discovered from a lagoon in El Nido, Palawan. To determine the protein content of the plant, an adequate amount of the plant extract was acquired, and Bradford assay was performed. Determine the total protein concentration, in µg/mL, of the acquired plant extract. A bovine serum albumin (BSA) stock solution with a concentration of 250 µg/mL was used and mixtures with the following compositions and absorbance readings were prepared: Volume of BSA (mL) Volume of water (mL) Absorbance Tube # at 595 nm 1 0.00 2.00 0.000 2 0.20 1.80 0.112 3 0.40 1.60 0.225 4 0.60 1.40 0.318 5 0.80 1.20 0.432 6 1.00 1.00 0.551 The absorbance reading of the plant extract is 0.275.

You are studying a biochemical pathway and isolate Neurospora 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 that shows the correct order for compounds X, Y, and Z and for the enzymes that each mutant is defective for.
