The nuclear matrix continues DNA synthesis at in vivo replicational forks.

Abstract

Alkaline cesium chloride gradient analysis of in vivo [3H]bromodeoxyuridine-labeled and in vitro [alpha-32P]dCTP-labeled DNA was used to determine whether in vitro DNA synthesis in regenerating rat liver nuclei and nuclear matrices continued from sites of replication initiated in vivo. At least 70 and 50% of the products of total nuclear and matrix-bound in… (More)
