Capturing hammerhead ribozyme structures in action by modulating general base catalysis.

abstract：:Understanding the molecular events that underlie the evolution of morphological diversity is a major challenge in biology. Here, to identify genes whose expression correlates with species-specific morphologies, we compared transcriptomes of two closely related Hydra species. We find that species-specific differences i...
