Physicochemical properties of microwave heated sago (Metroxylon sagu) starch by Zailani, Mohd Alhafiizh, Abd Razak, Hanisah Kamilah, Awang Husaini‬, ‪Awang Ahmad Sallehin, Sarbini, Shahrul Razid

“…The modified starches have irregular shaped granules and fissures while maintaining their mean diameters. The degree of double helix had increased, indicating more double helix structure of amylose formed. …”

Dilute iota- and kappa-Carrageenan solutions with high viscosities in high salinity brines by Iglauer, Stefan, Wu, Y., Shuler, P., Tang, Y., Goddard, W.

“…We explain these rheological phenomena with molecular processes, specifically the conformation change of the ι-Carrageenan from random coil to double helix. In the context of enhanced oil recovery, ι-Carrageenan solutions can reach much higher viscosities at high salinities than standard polyacrylamide solutions. …”

Modular ssDNA binding and inhibition of telomerase activity by designer PPR proteins by Spåhr, H., Chia, T., Lingford, J.P., Siira, S.J., Cohen, S.B., Filipovska, A., Rackham, Oliver

“…DNA is typically found as a double helix, however it must be separated into single strands during all phases of DNA metabolism; including transcription, replication, recombination and repair. …”

Untwisting of the DNA helix stimulates the endonuclease activity of Bacillus subtilis Nth at AP sites by Collier, Christopher, Machon, Cristina, Briggs, Geoff S., Smits, Wiep Klaas, Soultanas, Panos

“…We discovered that untwisting of the DNA double helix by bacterial non-specific DNA binding proteins stimulates the activity of a repair endonuclease of the Nth/MutY family involved in abasic site removal during base excision repair. …”

Fluorescence and molecular simulation studies on the interaction between imidazolium-based ionic liquids and calf thymus DNA by Jumbri, Khairulazhar, Kassim, Mohd Azlan, Mohamad Yunus, Normawati, Abdul Rahman, Mohd Basyaruddin, Ahmad, Haslina, Abdul Wahab, Roswanira

“…As predicted, the rod-like structure of imidazolium-based ILs prefers to bind to the double-helix DNA through a minor groove. Interestingly, the occurrence of T-shape π-π stacking was observed between the amine group in adenine that faces the aromatic ring of imidazole. …”

Initiation of DNA replication in Bacillus subtilis: structural studies of the DnaA-DnaD interaction by Martin, Eleyna

“…The role of the initiator proteins is to melt the DNA double helix and enable loading of the hexameric ring helicase onto each strand of DNA for bidirectional replication. …”

The discovery of hydrogen bonds in DNA and a re-evaluation of the 1948 Creeth two-chain model for its structure by Harding, Stephen E., Channell, Guy Andrew, Phillips-Jones, Mary K.

“…Crick, as acknowledged in ‘The Double Helix’. At that time of the discovery, however, it was impossible to delineate between inter- and intra-chain hydrogen bonds. …”

A molecular hydrodynamic study of marine based non-digestible fibre polysaccharides considered for use in health products by Almutairi, Fahad Mohammed

“…In addition, the effect of a wide range of solvent conditions was investigated to provide any evidence of dimerization/double helix formation for the main classes of carrageenan (kappa, iota and lambda) using the principal tools of hydrodynamics supported by micro-differential scanning calorimetry. …”

Secondary students' understanding of the gene concept : an analysis of conceptual change from multiple perspectives. by Venville, Grady J.

“…The process aspects of genetics content were said by teachers to be difficult to teach, and students found it difficult to link together ideas taught in genetics such as the double helix structure of DNA, the genetic code, protein synthesis and phenotypic expression. …”
