What reaction is catalyzed by DNA polymerase?

DNA polymerases catalyze efficient and high fidelity DNA synthesis. While this reaction favors nucleotide incorporation, polymerases also catalyze a reverse reaction, pyrophosphorolysis, removing the DNA primer terminus and generating deoxynucleoside triphosphates.

What phase does DNA polymerase occur?

As you can see in the image below, DNA replication takes place in the S-phase of the cell cycle, which is before the cell enters mitosis.

Which enzyme catalyzes DNA elongation during replication?

DNA polymerase catalyzes the elongation of a DNA strand in the 5′-3′ direction.

How is DNA polymerase a catalyst?

DNA and RNA polymerases (Pols) catalyze nucleic acid biosynthesis in all domains of life, with implications for human diseases and health. Pols carry out nucleic acid extension through the addition of one incoming nucleotide trisphosphate at the 3′-OH terminus of the growing primer strand, at every catalytic cycle.

What is the role of DNA polymerase quizlet?

What role does DNA polymerase play in copying DNA? DNA polymerase is an enzyme that joins indivisual nucleotides to produce a new strand of DNA. Replication in most prokaryotic cells starts from a single point and proceeds in two directions until the entire chromosome is copied.

Which polymerase is used in DNA replication?

DNA polymerase III holoenzyme
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.

What is the reaction in DNA replication catalyzed by DNA ligase?

What is the reaction in DNA replication catalyzed by DNA ligase? Explanation: DNA ligase catalyzes the formation of a phosphodiester bond between 3′-OH of one Okazaki fragment and 5′-phosphate of the next.

Which of the following occurs during DNA replication?

Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment.
