## Synopsis $elutions of calf thymus NaRNA in 0.2M NaCl and CsDNA in 0.2M CsCl (fragmented by sonic irradiation to a molecular weighb of about 5 X 106) were examined by electron microscopy, light scattering, and viscosity measurements. Electron microscopy showed that the molecular fragments are ro
We report measurements of the water content and swelling of wet-spun films of Na-, K-, Rb-, and Cs-DNA as a function of relative humidity ( r h ) . The water contents (number of water molecules per base pair of DNA) of these films are found to be quite similar, indicating that the identity of the co
The Raman spectra of calf thymus DNA in aqueous solution before and after irradiation in two UV regions (UVA, 320-340 nm; UVA-UVB, 280-400 nm) were investigated. Damage to the molecular structure in part was found in the DNA solution after UVA-UVB irradiation. The bands near 811 (ยฑ7) and 832 (ยฑ7) cm
