0 a chemical substance produced in the body that breaks connections in DNA (= the chemical that controls the structure and function of cells)

When the amplified fragment does not show size polymorphism between genotypes, restriction endonucleases can be further used to visualize inter-sequence polymorphism.
Firstly, its molecular mass is distinctly smaller than that of the single-stranded endonuclease.
The remaining two isolates were indistinguishable from each other by all three endonucleases.
To identify diagnostic sites, the four amplified sequences were analysed with a variety of restriction endonucleases.
The key is designed so that all identifications are based on at least two restriction endonucleases.
The overall stability of the genome is always under threat of endonuclease nicking and exonuclease digestion.
A cladistic analysis of phenotypic associations with haplotypes inferred from restriction endonuclease mapping.
The digestion with a single endonuclease did not differentiate interspecific patterns in just one assay.
