DNA aptamers and DNA enzymes

Area of Science:

• Biochemistry
• Molecular Biology
• Synthetic Biology

Background:

• Classical understanding depicts DNA primarily as a carrier of genetic information.
• Emerging research highlights DNA's potential beyond its genetic role.

Purpose of the Study:

• To explore the non-canonical structural and functional capabilities of DNA.
• To investigate DNA's potential as a catalyst and in forming complex structures.

Main Methods:

• Utilizing combinatorial approaches to explore DNA's structural diversity.
• Analyzing higher-ordered structural features in novel DNA assemblies.

Main Results:

• DNA can form highly specific receptors and ligands.
• DNA structures exhibit complex folding patterns, similar to ribozymes.
• DNA demonstrates catalytic activity, functioning as a deoxyribozyme.
• These DNA structures are not rare exceptions but represent a significant capability.

Conclusions:

• DNA possesses significant structure-forming potential, rivaling RNA.
• DNA can function as an enzyme (deoxyribozyme) despite lacking 2' hydroxyl groups.
• Novel DNA structures expand the understanding of DNA's functional repertoire.
