THE ISOLATION OF T4-SPECIFIC RNA ON A DNA-CELLULOSE COLUMN

Abstract
T4- specific RNA has been quantitatively separated from E. coli RNA by chromatography on columns made of T4 DNA linked to cellulose. Apparently, the basis of the fractionation is specific hydrogen-bond formation between the DNA of the column and RNA molecules complementary in base sequence. A DNA-cellulose column containing DNA from the T4 deletion mutant r1272 has been used to purify a type of RNA which appears to be specific for the rII region of the phage genome.
