Pna antisense
WebNov 19, 2024 · Peptide nucleic acid (PNA), an artificial DNA analog, comprises a purine or pyrimidine base and a pseudo-peptide backbone instead of deoxyribose-phosphate. PNA has been found to have stronger adhesion and higher stability in binding to its complementary DNA than deoxyribose-phosphate. WebPart II of the book addresses specific translational or clinical applications for PNA and related antisense biomolecules. The editors have succeeded in presenting a balanced yet broad view of the methods available for gene targeting and modification. Product Identifiers. Publisher. Springer. ISBN-10. 0306482304.
