In this article we will discuss about the six basic rules for DNA replication. The rules are: 1. Replication is a Semi-conservative Process 2. Replication has Direction 3. Replication Starts off a Unique Point on Bacterial and Viral Chromosomes 4. Replication of Both Strands Proceeds by the Addition of Nucleotide Monomers in the 5'-3' Direction and Others. Rule # 1.

In this article we will discuss about the rolling cycle method of DNA replication in φ X 174. All circular genomes do not follow the same pattern of replication described in E. coli. In some bacteriophages (phi, lambda and phi X 174), in mitochondrial chromosomes and during bacterial mating an alternative method known as the rolling circle has been demonstrated. [...]
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 [...]
