Hypochromic effect in dna
Web1 jun. 2024 · In general, the interactions of coordination compounds with DNA can be in three main ways: electrostatic interaction, with the oxygen atoms of phosphates; interaction in minor or major grooves hydrophobically and intercalating interaction between the stacked base pair of DNA. Heat denaturation of DNA, also called melting, causes the double helix structure to unwind to form single stranded DNA. When DNA in solution is heated above its melting temperature (usually more than 80 °C), the double-stranded DNA unwinds to form single-stranded DNA. The bases become unstacked and can thus absorb more light. In their native state, the bases of DNA absorb light in the 260-nm wavelength region. When the bases become unstacked, the wavelength of …

Web5 sep. 2014 · The interaction between idarubicin and double stranded deoxyribonucleic acid (ds-DNA) was investigated by UV-VIS spectrophotometry, fluorescence and Raman spectroscopy techniques. The absorption spectra of idarubicin with ds-DNA showed a slight red shift and hypochromic effect.
