摘要：

The simian virus 40 chromosome, a model for the mammalian replicon, is a uniquely powerful system for the study of drugs and treatments which target enzymes of the mammalian replication apparatus. High resolution gel electrophoretic analysis of normal and aberrant viral replication intermediates can be used effectively to understand the molecular events of replication failure. These events include breakage of replication forks, aberrant topoisomerase action, failure to separate daughter chromosomes, protein-DNA crosslinking, single and double strand DNA breakage, alterations in topology and inactivation of replication intermediates. The SV40 replication system can also be used to study the recombinational events which often follow drug-induced replication failure.
