- Repair enzymes : corrects almost all replication errors within the DNA polymerase complex, nucleases.
Mechanism of DNA Replication
Replication of the DNA molecule is a complex multistep process, each step precice controlled by a specific enzyme. First, the hydrogen bonds that maintain the helix and link is polynucleotide chains are broken. Next, the unbonded chains are separated and unwound, ace then complementary nucleotides are paired with each nucleotide on the parent chains. Fins the newly positioned nucleotides are covalently bonded together to form their own chs This is a very rapid process. In eukaryotic cells, 50 base pairs are formed per second, whilit prokaryotic cells the rate is 500 base pairs per second.
Origin of replication. Replication begins at the initiation site, called origin hi prokaryote (bacterium or virus), there is only one origin of replication, whereas in eukaryca with giant DNA molecules, there can be several origins of replication (these linearly arranged units are called replicons) which may merge with each other once replication is under prograi
Separation of two strands of a DNA molecule and new strand synthesis. The nex major step is the separation of two strands of DNA, each strand serves as a template for the synthesis of a hew strand. Formation of a new strand requires a primer. The primer is actua2 a short stretch of RNA formed on the DNA template, and the enzyme which polymerises RN building blocks (A, U, G, C) into primer is known as primase. The primer produces a 3.0He on the sequence of ribonucleotides, to which deoxyribonucleotides are added. The RNA prin is ultimately removed leaving a gap in the newly synthesised deoxyribonucleotide strand 1 removed from 5' end one by one by the exonuclease activity of DNA polymerase.
