Mismatch repair or when DNA went separate ways, a Nobel prize was given for the discovery of DNA’s ability to regenerate itself, it’s called mismatch repair; for many year I’ve been absorbed with the need of science to create physical models of different phenomenon, mostly known as atom models, and everyone thinks that the atom looks like that, but no, it’s a practical tool, people need something physical to relate to, an image. The well-known DNA model, the double spiral, has over time assumed more and more complex shapes.
