Is the phosphate backbone of dna hydrophilic
Witrynarepeats its twist every ~10 nucleotides. The phosphate-sugar groups constitute the backbone of the helix; the bases, which lie perpendicular to the long axis, are spaced at 3.4 angstrom intervals. The DNA double helix has two grooves: the major groove and minor groove. Proteins can bind

WitrynaOne approach of fouling control is the use of hydrophilic polymer coatings made from poly-anions and poly-cations using the layer-by-layer (LBL) method. The authors hypothesized that the poly-anionic properties and the poly-phosphate backbone of DNA would provide anti-biofouling and anti-scaling properties.
