There are a few differences between the prokaryotic and eukaryotic replication processes. However, both of them include the general same steps. 1:Replication fork/2:Unreplicated DNA/3:Origin of replication/4:New DNA
--------------------------
Eukaryotic DNA replication process
DNA Replication starts in some specific place named replication origin. Eukaryotic cells have many replication origens.
Helicase
- This is the first enzyme that works in the replication origin.
- It separates the DNA into two strands allowing the replication forks to advance by unwinding the DNA.
- It breaks hydrogen bonds between nitrogenated bases pairs.
Topoisomerase impedes the DNA double helix near the replication forks to get too coiled when the DNA is opening.
DNA polymerase III
- This enzyme is responsible for DNA elongation.
- It is in charge of adding nucleotides to the growing chain, from 3' to 5' extremes.
- It includes only nucleotides that complement the original strand.
- They need to recognize a primer to begin.
Primase is in charge of synthesizing primers.
DNA polymerase I eliminate ARN primers and substitute them with DNA.
DNA ligase seals the gaps that remain after replacing the primers.
*************************************
Prokaryotic DNA replication process
The prokaryotic replication process involves the double helix unwinding and opening from an origin point, which is the replication origin.
Prokaryotic cells only have one replication origin.
Proteins DNA A
They recognize the replication origin and are responsible for the beginning of the process.
Helicase
- This enzyme works in the replication origin breaking the hydrogen bonds between nitrogenated bases pairs
- It separates the DNA into two strands allowing the replication forks to advance by unwinding the DNA.
DNA polymerase I and III
- Enzymes that are in charge of DNA elongation by adding nucleotides.
- They synthesize the new strains.
- They correct mistakes produced during the synthesis.
Endonuclease
- In charge of eliminating mistakes.
- They cut the erroneous segment.
DNA ligase seals the gaps that remain after cutting segments.
