What is the major difference between prokaryotic and eukaryotic DNA replication?
Prokaryotic Replication vs Eukaryotic Replication
Prokaryotic Replication | Eukaryotic Replication |
---|---|
It is a continuous process. | This process occurs in the S-phase of cell cycle. |
Circular, double-stranded DNA | Linear, double-stranded DNA with end |
The DNA replicates in the cytoplasm | The DNA replicates in the nucleus |
Is DNA polymerase found in eukaryotes and prokaryotes?
The number of DNA polymerases in eukaryotes is much more than prokaryotes: 14 are known, of which five are known to have major roles during replication and have been well studied. They are known as pol α, pol β, pol γ, pol δ, and pol ε. The essential steps of replication are the same as in prokaryotes.
What DNA polymerase do eukaryotes use?
Eukaryotes utilize three essential B family DNA polymerases for genome replication: Pol α, Pol δ, and Pol ε (9). Each of these B family DNA polymerases is highly conserved from yeast to human (9).
Do prokaryotes have DNA polymerase?
In prokaryotes, three main types of polymerases are known: DNA pol I, DNA pol II, and DNA pol III. DNA pol III is the enzyme required for DNA synthesis; DNA pol I and DNA pol II are primarily required for repair. There are specific nucleotide sequences called origins of replication where replication begins.
What are the 5 types of DNA polymerase in eukaryotes?
The eukaryotic cell contains five DNA polymerase α, β, γ, δ, and ε.
Is DNA polymerase 1 in eukaryotes?
Eukaryotic cells contain 5 different DNA polymerases: α, β, γ, δ, and ε. coli DNA Pol I because its main function is associated with DNA repair, rather than replication. DNA polymerase β is mainly used in base-excision repair and nucleotide-excision repair.
