*estimation is based on the velocity in an electric field. High molecular RNA-fractions of Eschericia coli with molecular weights of 1.1 and 0.56 x 106 were chosen as reference values. + calculated from the molecular weights and referring to the 1541 nucleotides containing rRNA of Eschericia coli |
