On the Probability of Codon−Codon Mutational Replacements

Journal of Chemical Information and Computer Sciences, 1997
The content of the data base of blocks of protein sequences (Henikoff, S. ; Henikoff, J. G. Genomics 1994, 19, 97−107) were used in order to locate the homologous gene sequences. Aligning these sequences the 64 × 64 matrix of codon−codon interchanges was constructed. Matrices were generated for various phylogenetical groups of organisms and for various

Codon reassignment (codon capture) in evolution

Journal of Molecular Evolution, 1989
The genetic code, once thought to be "frozen," shows variations from the universal code. Variations are found in mitochondria, Mycoplasma, and ciliated protozoa. The variations result from reassignment of codons, especially stop codons. The reassignments take place by disappearance of a codon from coding sequences, followed by its reappearance in a new

On Codon reassignment

Journal of Molecular Evolution, 1995
Schultz and Yarus (J. Mol. Biol. 235:1377-1380, 1994) have proposed that reassignment of codons in the genetic code passes through a stage in which the codons are ambiguously translated. In contrast we state that such ambiguity would be deleterious, and that, to be reassigned, a codon, together with the tRNA that translates the codon, must first ...

Codon context

Experientia, 1990
The analysis of coding sequences reveals nonrandomness in the context of both sense and stop codons. Part of this is related to nucleotide doublet preference, seen also in non-coding sequences and thought to arise from the dependence of mutational events on surrounding sequence.
