The tertiary structure of dna
WebDNA supercoiling describes a higher-order DNA structure. The double-helical structure of DNA entails the interwinding of two complementary strands around one another and around a common helical axis. The writhing of this helical axis in space defines the DNA superhelical structure (DNA tertiary structure). For a circular DNA or a linear DNA ... WebDNA. DNA quaternary structure is used to refer to the binding of DNA to histones to form nucleosomes, and then their organisation into higher-order chromatin fibres. The quaternary structure of DNA strongly affects how accessible the DNA sequence is to the transcription machinery for expression of genes. DNA quaternary structure varies over time, as regions …

These determine the general three-dimensional form of local segments of the biopolymers, but does not describe the global structure of specific atomic positions in three-dimensional space, which are considered to be tertiary structure.Secondary structure is formally …
WebThe free energy of an RNA fold is a combination of favorable base pairing and stacking interactions competing with entropic costs of forming loops. Here we show how loop entropy, surprisingly, can promote tertiary order. A general formula for the free energy of forming multibranch and other RNA loops is derived with a polymer-physics based theory. …
