the electrophoretic mobilities of ribosomal ribonucleic acids ( rna ) from cultured mammalian ( hela , vero , mdbk ) , avian ( chick embryo ) , and bacterial ( escherichia coli ) cells , and rna species extracted from selected viruses ( sindbis , polio , tobacco mosaic , sendai ) were compared , employing a simple , inexpensive technique for slicing low-concentration polyacrylamide gels .
