Plasmids and extrachromosomal DNA share key evolutionary capacities, acting as contingency loci that enable rapid adaptation across bacteria and cancer cells.
- Why it matters: Understanding how extrachromosomal DNA contributes to genetic diversity and adaptation is crucial, as it may reveal fundamental principles of evolution and mechanisms of disease progression.
- What they did: The study compares formation, expression, segregation, and evolution of plasmids and ecDNA, highlighting common principles and open questions through a detailed analysis.
- The result: Findings suggest that both types of extrachromosomal DNA function as convergent evolutionary solutions, promoting heterogeneity and rapid adaptation in diverse biological contexts.
