In this article we will discuss about the DNA replication in eukaryotes. In eukaryotes there are only two different types of DNA polymerases in contrast with DNA polymerase I, II and III of prokaryotes. Furthermore the DNA of eukaryotes is a long linear molecule with several replication units. A diploid mammalian cell contains on an average about 6 pg of [...]
The Watson-Crick model of DNA has been the basis for further work on DNA replication, mutation and recombination. Much evidence exists to establish the validity of this model. Nevertheless, the model has been scrutinized by other workers, and from time to time other models have been suggested by Wu (1970), Arnott (1968), Wang (1979) and a few others. Wang's model [...]
