Evolutionary Implications of Genetic Code Deviations

摘要

By extending the standard genetic code into a temperature dependent regime, the authors propose a train of molecular events leading to alternative coding. The first few examples of these deviations have already been reported in some ciliated protozoans and Gram positive bacteria. A possible range of further alternative coding, still within the context of universality, is pointed out. 26 references, 3 tables. (ERA citation 12:029395)
