Peptide nucleic acid (PNA) is an oligomer, in which the phosphate backbone has been replaced by a pseudopeptide backbone that is meant to mimic DNA. Peptide nucleic acids are of the utmost importance ...

Nucleic acids may be labeled at their 3’ end, 5’ end, or throughout the molecule, depending on the desired application. Myriad of enzymatic or chemical methods are utilized to generate nucleic acids ...

A DNA strand (purple) primes exponential amplification of DNA (red) as signals for directing light emission of DNA nanodeveices. [Organic and Biomolecular Chemistry] Scientists in Japan say they have ...

In the case of nucleic acid tests, polymerase chain reaction (PCR) has been the gold standard for single-molecule diagnosis. Single-molecule detection of pathogens, such as severe acute respiratory ...

Nucleic acids are complex biological molecules that store and transmit genetic information in all living organisms. They are essential for the survival and reproduction of life on Earth. The two main ...
