Question

In yeast, there are three gene products required to synthesize the amino acid lysine. You cross two haploid lysine auxotrophs to form a diploid. The diploid fails to grow on plates lacking lysine. Which of the following can you definitively conclude? O The haploid strains have identical mutations in different genes. The haploid strains have mutations in different genes The hapoid erains mblentation group encoding the first enzyme in biosynthetic pathway. The haploid strains have identical mutations in the same genes O The haploid strains have mutations in the same gene.

Explanation / Answer

Auxotroph - Some micro-organism loose the ability to synthesize an organic compound which is necessary for its growth.Usually this is done by mutation.

Ans- The haplois stains have mutation in the same genes. These haploid stains does not complement of each other
