Mathematical model for studying genetic variation in terms of restriction endonucleases.
As a result, it is widely believed that the actual and potential site recognition repertoires of homing endonucleases are extremely broad.
The upper panels show results of endonuclease analysis.
Similar alignments of intein-associated endonuclease domains indicate a more diverged structure of the b-sheet motifs.
Mathematical model for studying genetic variations in terms of restriction endonucleases.
The existence of multiple evolutionarily distinct families of homing endonucleases indicates several independent ancestral origins for these elements.
However, it does appear possible that a small fraction of homing endonuclease genes have evolved a more host-beneficial role.
The digestion with a single endonuclease did not differentiate interspecific patterns in just one assay.
