Two arginine requiring mutants arg-4 and arg-5 were isolated in Neurospora. When the strains were grown alone on media without arginine they do not grow. When they were crossed to each other, the diploid F1 could grow in the absence of arginine. The table below shows whether mutants grow with the media supplemented with ornithine, citrulline, or arginine. (-- is no growth, + is growth). Answer the two following questions. Pathway: Orthinine Citrulline → Arginine Mutant arg-5 arg-4 Media Supplement Ornithine Citrulline + Arginine + +
