Intercalation induces structural distortions. Left: unchanged DNA strand. Right: DNA strand intercalated at three locations (black areas). In biochemistry, intercalation is the insertion of molecules between the planar bases of deoxyribonucleic acid (DNA). This process is used as a method for analyzing DNA and it is also the basis of certain ...
DNA crosslinks generally cause loss of overlapping sequence information from the two strands of DNA. Therefore, accurate repair of the damage depends on retrieving the lost information from an undamaged homologous chromosome in the same cell. Retrieval can occur by pairing with a sister chromatid produced during a preceding round of replication.
Based on the properties of intercalating molecules, i.e. fluorescing upon binding to DNA and unwinding of DNA base-pairs, in 2016, a single-molecule technique has been introduced to directly visualize individual plectonemes along supercoiled DNA [5] which would further allow to study the interactions of DNA processing proteins with supercoiled DNA.
DNA-binding metallo-intercalators are positively charged, planar, polycyclic, aromatic compounds that unwind the DNA double helix and insert themselves between DNA base pairs. [1] Metallo- intercalators insert themselves between two intact base pairs without expelling or replacing the original nitrogenous bases ; the hydrogen bonds between the ...
However, branched DNA can occur if a third strand of DNA is introduced and contains adjoining regions able to hybridize with the frayed regions of the pre-existing double-strand. Although the simplest example of branched DNA involves only three strands of DNA, complexes involving additional strands and multiple branches are also possible. [69]
In biochemistry, intercalation is the insertion of molecules between the bases of DNA. This process is used as a method for analyzing DNA and it is also the basis of certain kinds of poisoning. Clathrates are chemical substances consisting of a lattice that traps or contains molecules. Usually, clathrate compounds are polymeric and completely ...

As a nucleic acid structure, i-motif DNA stability is dependent on the nature of the sequence, temperature, and ionic strength. The structural stability of i-motif DNA is mainly reliant on the fact that there is minimal overlap between the six-membered aromatic pyrimidine bases due to the consecutive base pairs' intercalative geometry.
