Introduction
Peptide nucleic acid (PNA) is a novel DNA analog with a peptide backbone. PNA is synthesized artificially. No known individual organisms on Earth have been found to possess PNA in their bodies. The backbone of PNA is composed of repeatedly arranged N-(2-aminoethyl)-glycine units, which are assembled by peptide bonds. The bases are linked to the backbone by methylene carbonyl bonds. PNA also has an N-terminal (nitrogen-terminals) and a C-terminal (carbon-terminals).

Characteristics of PNA
- PNA molecules have structural characteristics similar to those of natural DNA molecules
- PNA can form dimers of target genes
- PNA has the same characteristics of binding to specific DNA and RNA molecules as oligonucleotides
- PNA works by forming a three-stranded helix structure with target genes
Advantages of PNA
- PNA can be synthesized from monomers
- Resistant to degradation by nucleases and proteases
- Good water solubility and stability
- PNA requires a shorter sequence length than DNA
- PNA binding to DNA requires only a low salt reaction environment
Application of PNA
- miRNA inhibitors
- Double-stranded DNA invasion and capture
- Microarray probes
- For fluorescence in situ hybridization (FISH) analysis
- Sequence-specific PCR inhibitors (PNA clamps)
- Genome excision and mapping analysis
- Gene expression regulation
- As antisense drugs
