Figure 1From: Constructive neutral evolution: exploring evolutionary theory’s curious disconnectGene scrambling. In a post-mating ciliate cell (right), the micronucleus divides, and one daughter is converted into a new macronucleus (gray circle) as the old macronucleus (gray oval) degenerates. Processing to generate macronuclear genes (left) includes removal of intervening segments (black bars) and unscrambling of segmented genes.Back to article page
