Description
DNA replication is a crucial biological procedure that ensures the precise copying of genetic material prior to cell division. This process guarantees the transfer of genetic information from one generation to the next. While the overall mechanism of DNA replication is similar across all life forms, significant differences can be observed between prokaryotic and eukaryotic systems, largely due to variations in the structure of the genome, cellular organization, and the enzymes involved. The DNA replication process operates on a semi-conservative model, where each daughter DNA molecule consists of one strand from the parent and one newly formed strand. In prokaryotes, DNA replication generally initiates at a single origin and utilizes a relatively straightforward set of enzymes, whereas eukaryotic replication is more intricate because of larger genomes, linear chromosomes, and multiple sites of replication. This chapter describes the basic principles of DNA replication and provides a comparative analysis of replication mechanisms in prokaryotic and eukaryotic organisms.
