“Conclusion: Big helix in several chains, phosphates on outside, phosphate-phosphate inter-helical bonds disrupted by water. Phosphate links available to proteins.”
About This Quote
Source Scientific paper: X-ray diffraction study of DNA, 1952
The DNA double helix consists of multiple chains with external phosphates; water disrupts inter‑phosphate bonds, making phosphates accessible to proteins.
In simple terms: DNA structure has exposed phosphates that interact with proteins.
Key Takeaway
Consider how water and protein interactions affect DNA stability.

A Different Perspective
The model oversimplifies dynamic cellular environments where other factors influence DNA behavior.
![“In describing a protein it is now common to distinguish the primary, secondary and tertiary structures. The primary structure is simply the order, or sequence, of the amino-acid residues along the polypeptide chains.
