Describe Genetics

The mitochondrial ATP synthase is unruffled of multiple proteins and some of these proteins are encoded by genes in the nucleus. One of these proteins is called S. A mutation in the S gene erases 21 base pairs that are immediately 3' to the start codon. The mutant S gene is transcribed as well as translated but the S protein remains in the cytoplasm. This mutant yeast cell can merely grow anearobically whereas wild kind yeast can grow anaerobically or aerobically. Yeast grows as a haploid cell. In wild kind cells in the presence of O2, the pH of the mitochondrial matrix is 8 however in cells with this mutant S gene, the pH is 7. Please describe these results
