Mechanism of DNA chain growth. IV. Direction of synthesis of T4 short DNA chains as revealed by exonucleolytic degradation

Mechanism of DNA chain growth. IV. Direction of synthesis of T4 short DNA chains as revealed by exonucleolytic degradation

T Okazaki et al. Proc Natl Acad Sci U S A. 1969 Dec.

Abstract

T4 nascent short chains labeled at their growing ends with H(3)-thymidine and uniformly with C(14)-thymidine were prepared, separated into complementary strands, and degraded by E. coli exonuclease I in the 3' to 5' direction or by B. subtilis nuclease in the 5' to 3' direction. The kinetics of release of H(3) and C(14) labels by both enzymes was consistent with the conclusion that the H(3) label is at the 3' end of the nascent short chains of both strands and that the short chains are products of discontinuous synthesis in the 5' to 3' direction along the two template strands.
