Practice question

Neoschizomers recognize the same nucleotide sequence but hydrolyze phosphodiester bonds at different positions, thereby generating distinct fragment ends. Discrimination between isoschizomers, neoschizomers and isocaudomers is essential for mapping. HpaII and MspI both recognize CCGG, representing canonical tetranucleotide containing CpG methylation sensitivity. HpaII cleaves C/CGG, producing 5' CG overhang, while MspI is often taught as cutting at C/CGG as well but historic textbook classifications list them as neoschizomers due to differing cleavage sensitivity and context-specific cut variations. Their shared recognition with divergent cutting behavior exemplifies neoschizomer definition used in examinations.
