Kinked DNA
Article Abstract:
Atomic force microscope images images show deoxyribonucleic acid (DNA) molecules become kinked in the presence of specific divalent cations such as Zn2+. This research establishes tandem sequence repeats of d(A)s and d(GGGCC[C])s cause DNA to kink. Bending DNA molecules may be more prevalent at some locations of the DNA molecule. DNA molecules of up to 126-base-pairs long are the maximum length before a superhelix is formed.

Tight knot values deviate from linear relations
Article Abstract:
Research demonstrates that an infinite number of knots can be created in the biochemical molecule deoxyribonucleic acid with a minimum rope length power of 3/4. The geometric relationship between knot types is discussed. Further research is required to establish if knot families exhibit superlinear growth patterns.
