WebMar 8, 2024 · Expression of the aadA gene is positively regulated by the stringent response regulator (p)ppGpp and these results show how slow-growth environments (or mutations that confer slow growth by impairing electron transport) that increase (p)ppGpp levels can activate a gene that is usually silent (Koskiniemi et al. 2011). WebJun 9, 2024 · 4.1.4: Studying Evolution in Action. Today, we recognize that evolution takes place through a combination of mechanisms: mutation, genetic drift, gene flow, and natural selection. These mechanisms are called the “forces of evolution” and together they can account for all the genotypic variation observed in the world today.
