Replication in eukaryotes is slower than in prokaryotes; it is 100 base pairs per second. While there are many similarities in how prokaryotic and eukaryotic cells replicate their DNA, there are several distinctions between them, due to the different size and complexity of the molecules, including the time it takes to complete the process.
Prokaryotic DNA replication is a continuous process. The final product of the eukaryotic DNA replication is two sister chromatids. The termination of DNA replication occurs at specific termination sites in both prokaryotes and eukaryotes.
The steps for DNA replication are generally the same for all prokaryotic and eukaryotic organisms. The nicks are joined by the DNA ligase. Both prokaryotic and eukaryotic DNA replications are semi-conservative DNA replications in which one old and one new strand can be found in the daughter cell.
During DNA replication, the synthesis of one strand occurs in a continuous manner, whereas that of the other strand occurs in a discontinuous manner through the formation of fragments. DNA Replication Enzymes.
Regarding biology, we use replication word in the reproduction or copying of DNA in the cell to produce its identical copies. Though the process of DNA replication is nearly similar in both prokaryotes and eukaryotes, some differences may occur due to the size and the complexity of the genetic material.
Although a similar set of enzymes are involved in prokaryotic and eukaryotic DNA replication, the latter one is more complex and varied. One of the major difference between prokaryotic DNA replication and eukaryotic DNA replication is that prokaryotic replication occurs inside the cytoplasm of the cell whereas, eukaryotic replication of DNA occur inside the nucleus.
However, in certain plasmids present in bacterial cells, unidirectional DNA replication has been observed. Differences between prokaryotic and eukaryotic DNA replication are largely related to contrasts in size and complexity of the DNA and cells of these organisms. All Rights Reserved. DNA deoxyribonucleotide , a.
If DNA replication was dependent on a single replicon, it would take a month's time to finish replicating one chromosome. Organelles and Their Functions. Essentials of Genetics The Cell: However, due to the size and the complexity of the eukaryotic genome, the eukaryotic DNA replication is a more complex process.
The process of DNA replication in prokaryotes is shown in figure 1. Eukaryotic DNA have a large number of replications 50,000 or more , but it is not sudden. Life Cycle of a Bean Plant.
