the interaction of ethidium bromide ( etbr ) with double helical synthetic polyribonucleotides poly ( g ) .poly ( c ) , poly ( a ) .poly ( u ) and poly ( i ) .poly ( c ) has been investigated by the method of isothermal microcalorimetry and according to the character of changes on the spectra of circular dichroism , absorption and fluorescence at binding .
