WebThe petite phenotype results from mutations in the mitochondrial genome, loss of mitochondria, or mutations in the host cell genome. The latter mutations affect nuclear-encoded genes involved in oxidative phosphorylation and these mutants are termed neutral petites. They all produce wild-type progeny when crossed with a wild-type strain. Web4. okt 2024 · Mutation – A change in a gene’s structure caused by a change in the nucleotide sequence in DNA.
