Researchers from Sheba and Meir Medical Center are tracking DNA and RNA from the tumor throughout treatment. In 15%–20% of patients, a signature of DNA segments was found that changed as the tumor shrank.

Engineered ribozyme demonstrates how ancient RNA could have repaired itself

An enzyme made of RNA selectively recognizes a chemical mark that characterizes broken strands and attaches additional RNA to them. The discovery strengthens the possibility that ancient life in the RNA world could have preserved genetic information even without proteins
