In this article we will discuss about the meaning of transformation. Transformation is the process of adding a foreign DNA fragment from a donor genome into genome of a recipient cell. The donor fragment passes through the cell membrane of the recipient cell (which may or may not belong to the same species) and becomes incorporated into the latter's genome [...]
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 [...]
In this article we will discuss about the introduction and mechanism of DNA replication. Introduction to DNA Replication: While presenting the double helical model of DNA, Watson and Crick had remarked, "It has not escaped our notice that the specific pairing (of bases) we have postulated suggests a possible copying mechanism for the genetic material." The complementary nature of the [...]
