DNA polymerase DNA polymerase III holoenzyme is the primary enzyme involved in DNA replication in E. coli and belongs to Family C polymerases. It consists of three assemblies: the pol III core, the beta sliding clamp processivity factor and the clamp-loading complex.hese enzymes are essential to DNA replication and usually work in pairs to create two identical DNA strands from a single original DNA molecule. During this process, DNA polymerase “reads” the existing DNA strands to create two new strands that match the existing ones.

DNA replication DNA polymerases are a family of enzymes that carry out all forms of DNA replication. DNA polymerases in general cannot initiate synthesis of new strands, but can only extend an existing DNA or RNA strand paired with a template strand.n a cell, DNA replication begins at specific locations, or origins of replication, in the genome. Unwinding of DNA at the origin and synthesis of new strands results in replication forks growing bidirectional from the origin.

Structural Biochemistry/Nucleic Acid/DNA/Replication Process/DNA Polymerase DNA polymerase is an enzyme. This enzyme synthesizes a new DNA strand from an old DNA template and also works to repair the DNA in order to avoid mutations. DNA polymerase catalyzes the formation of the phosphodiester bond which makes up the backbone of DNA molecules.he reaction catalyzed by DNA polymerases that works to elongate the chain is a nucleophilic attack by the 3’OH terminus of the growing chain on the innermost phosphorus atom of the deoxynucleotide triphosphate. Therefore, a primer strand with a free 3'-OH group must be bound to the template strand from the start.

Structural Biochemistry/Nucleic Acid/RNA/RNA Polymerase RNA polymerase is an enzyme that produces RNA and catalyzes the initiation and elongation of RNA chains from a DNA template. RNA is created using a process known as transcription. The RNA polymerase is a key component to this process. The reaction that this enzyme catalyzes for is: (RNA)n + Ribonucleoside Triphosphate ->/<- (RNA)n+1 +PPi. RNA polymerases are relatively large. The size of RNA polymerase in a typical eukaryotic cell is roughly 500kDa.

How does DNA polymerase work? The DNA polymerases are enzymes that create DNA molecules by assembling nucleotides, the building blocks of DNA. These enzymes are essential to DNA replication and usually work in pairs to create two identical DNA strands from a single original DNA molecule.ence, DNA polymerase moves along the template strand in a 3'-5' direction, and the daughter strand is formed in a 5'-3' direction. This difference enables the resultant double-strand DNA formed to be composed of two DNA strands that are antiparallel to each other.

DNA polymerase The 3'-5' exonuclease activity of the enzyme allows the incorrect base pair to be excised (this activity is known as proofreading). Following base excision, the polymerase can re-insert the correct base and replication can continue forwards.
