Triple Helix: Designing a New Molecule of Life

What is a human being? What is life? Can science give us reliable answers to such questions? The electricity of life. The meaning of human consciousness. Are we alone? Are the traditional contests between science and religion still relevant? Does the word "spirit" still hold meaning today?

Triple Helix: Designing a New Molecule of Life

Peptide nucleic acid, a synthetic hybrid of protein and DNA, could form the basis of a new class of drugs—and of artificial life unlike anything found in nature,

Key Concepts
A synthetic molecule called peptide nucleic acid (PNA) combines the information-storage properties of DNA with the chemical stability of a proteinlike backbone.

Drugs based on PNA would achieve therapeutic effects by binding to specific base sequences of DNA or RNA, repressing or promoting the corresponding gene.

Some researchers working to construct artificial life-forms out of mixtures of chemicals are also considering PNA as a useful ingredient for their designs.

PNA-like molecules may have served as primordial genetic material at the origin of life
Peptide nucleic acid (gold) readily enters DNA's major groove to form triple-stranded and other structures with DNA, allowing it to modify the activity of genes in new ways
