Which of the following is a key difference between eukaryotic and prokaryotic DNA replication

DNA is the cell’s genetic material, passed down to daughter cells. As a result, the entire DNA molecule should be replicated before cell division. As a result, DNA replication is a fundamental process in all organisms, whether prokaryotic or eukaryotic. Using the current DNA molecule as a template, the DNA replication process generates two identical copies of daughter DNA molecules. The replication mechanism in eukaryotic and prokaryotic species is very similar, with few variances.

The differences in replication between prokaryotic and eukaryotic organisms are primarily due to variations in genomic size and complexity. The eukaryotic cell has much more DNA than the prokaryotic cell, which is tightly packed as a chromosome in the eukaryotic cell’s nucleus. For example, the human genome is about 1000 times bigger than the E. coli genome.

Eukaryotic and Prokaryotic Replication: Differences

Prokaryotic Replication

Prokaryotic replication is when prokaryotes are archaea and bacteria repeat their genome to create a copy that may be turned into a daughter. In their cytoplasm, prokaryotes have a double-stranded circular molecule. Prokaryotic DNA has a single replication origin. By disrupting the hydride bonds between the nitrogen bases, helicase unwinds at the replication site. The replication fork is the resulting Y shaped structure. Because prokaryotic DNA has a single replication origin, only 2 replication forks are generated throughout the cloning process. These two cloning forks work in both directions.

Single strand DNA binding protein stabilizes the two unwinding strands that act as replication template strands. RNA primase is an enzyme that produces a 5-10 base pair prolonged RNA basal complementary to the template strand.

Eukaryotic Replication

The process by which the eukaryote replicates before cell division is known as eukaryotic DNA replication. Though the underlying process of eukaryotic replication is identical to that of prokaryotic replication, there are notable changes owing to eukaryotic DNA’s size and structure. DNA in Eukaryotes is made up of double wrecked linear molecules. The quantity of eukaryotic DNA is about fifty times more than prokaryotic DNA. Furthermore, eukaryotic DNA is densely filled with histones within the cell’s nucleus. As a result, DNA replication happens in three stages: initiate, elongate, and terminate.

Eukaryotic and Prokaryotic Replication: Similarities

1. Before entering the nuclear division, both eukaryotic and prokaryotic DNA replications occur.
2. Double-stranded DNA is used in both bacterial and eukaryotic replication.
3. DNA helicase is responsible for the unravelling of both eukaryotic and prokaryotic DNA.
4. Single-wrecked DNA-binding protein stabilizes the unwinding DNA swrecks(SSB).
5. DNA replication is a multistep process carried out by an enzyme complex known as DNA polymerases in prokaryotic and eukaryotic cells.

Eukaryotic and Prokaryotic Replication: Differences

Conclusion

DNA replication in eukaryotic and prokaryotic cells is involved in genome duplication before cell division. Both bacterial and eukaryotic replication mechanisms are comparable. However, eukaryotic replication is a more tough process due to the eukaryotic genome’s size and complexity. As a result, eukaryotic DNA replication takes place by developing numerous replication origins. On the other hand, prokaryotic replication proceeds through a single cloning origin. However, because prokaryotic replication occurs quickly, both replication processes require the same amount of time. As a result, the primary distinction between eukaryotic and prokaryotic replication is based on the complexity and size of each kind of genome.
