The CoRR hypothesis, or 'co-location for redox regulation,' explains why certain genes are retained in eukaryotic cell organelles like mitochondria and chloroplasts. It suggests that the proximity of these genes to their gene products is crucial for regulating gene expression in response to the redox state. This concept supports the endosymbiotic theory and provides insight into the evolutionary conservation of organelle genomes, highlighting the importance of redox regulation in cellular energy dynamics.
