PNA is an analog of the DNA molecule and is considered an important branch of future biotechnology because it is easier to use and process than DNA. The full name of PNA is polyisophenyl amino acid (Polyamide Nucleic Acid), which is a synthetic nucleic acid analog. Unlike DNA, PNA does not require a specific cellular enzyme system to encode and decode information in cells, which makes it widely used in life sciences and medical research.

PNA has the following important characteristics:

1. PNA has very stable chemical properties. Since the molecular chain of PNA does not contain hydrogen bonds, it is not easily broken. PNA can be stable at high temperature, which makes it has a wide range of potential for high temperature sterilization or disinfection applications.

2. PNA does not contain deoxyribose phosphate groups (dNTP) on the molecular chain, so PNA can react on its own without affecting the normal physiological activities of cells.

3. PNAs can avoid the complexities involved in the biological fabrication of cells. PNA is not found in nature. From a chemical point of view, it is easier to synthesize than DNA, which means that PNA is cheaper to make and easier to operate than DNA.

4. PNA has a strong ability to interact with DNA. Such interactions include DNA-RNA tandem, single-chain specific binding, and targeted recognition. Therefore, we usually use PNA to induce DNA strand shortening, which can also be used for DNA sequencing, DNA screening and DNA modification.

At present, PNA is mainly used in biomedical field. PNAs can be used as tools in cell biology or molecular biology research, for example, in the fields of mirror nucleic acid technology (MNA) and sensitive and specific nucleic acid probes (SMART). In the fields of pharmaceutical research and chemical genomics, PNAs can also be used to synthesize a variety of molecules that can bind to target proteins.

PNA is a very important molecule, which will have a wide range of applications in the field of biotechnology in the future. It can take advantage of the unutilized physical and chemical properties of human cells to develop new medical treatments. The researchers believe that with the use of PNA tools and the development of skilled technology, we will master new therapeutic technologies and leapfrog development of existing medical and life science technologies.
