Hypochromic effect on dna
Web11 apr. 2014 · When strands are denatured, the close interaction of stacked bases are has no effect (does not hinder) the absorption of UV radiation. Therefore denaturation of … 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 …
