A STABILITY THEOREM FOR FUNCTIONAL-DIFFERENTIAL EQUATIONS.

complementary RNA enzymatically synthesized on a template of total aDNA; anRNA: RNA enzymatically synthesized on a template of CaLDNA; aRNA: P32 pulse-labeled RNA isolated from infected cells and purified by aDNA hybrid formation; aL and alHDNA: the pyrimidine-rich and purine-rich isolated polynucleotide strands of aDNA; URP32 PP: uridine triphosphate labeled in the ribose-proximal phosphate with P32; A, G, C, U, and T: adenine, guanine, cytosine, uracil, and thymine; Tris: tris(hydro-symethyl) aminomethanol; SSC: "standard saline citrate," which is 0.15 M NaCl, 0.015 M sodium citrate pH 7; 2 SSC: double-concentration SSC.
