Gene regulatory networks show robustness to perturbations . Previous works identified robustness as an emergent property of gene network evolution but the underlying molecular mechanisms are poorly understood . We used a multi-tier modeling approach that integrates molecular sequence and structure information with netw... | Development from egg to embryo depends to a large extent on regulatory networks of genes called transcription factors . Previous research has shown these gene regulatory networks to be robust to perturbations at the level of the connections between transcription factors .
