2. What are petite yeasts? In certain yeasts, abnormally small colones occur. The cells that form petite colonies are mutants that lack certain components for respirtation; therefore, they exhibit a reduced growth rate. Mutations occur in nuclear DNA or in mitochondrial DNA. Mitochondria are "organelles" found in most eukaryotic cells. They are the sites for cellular respiration and other cellular processes. Occurrence is one in 500. back to questions
