The Scripps Research Institute issued the following news release:

* * *

- Mitochondrial transfer-RNAs evolved special mutation-resilient structure in complex animals.

* * *

A set of molecules needed for efficient energy production in cells apparently underwent a radical change during early animal evolution so they could continue to function despite their relatively high mutation rate, according to a new study from scientists at Scripps Research.

In the study, publis...
