Topoisomerase is the enzyme that relieves tension to the DNA molecule by nicking and cutting certain placed on the phosphate backbone.
Helicase is the next enzyme that is involved in "unzipping" the DNA to produce two single strands of DNA.
RNA polymerase lays down the RNA primer
DNA polymerase III uses the RNA primer to start laying down new nucleotides on the single strand of DNA.
DNA polymerase I replaces the RNA primer with DNA
DNA ligase creates joins the backbone of the newly formed DNA strands

Examples of intracellular enzymes?
Examples of intracellular enzymes include catalase, an enzyme that breaks down hydrogen peroxide in cells, and DNA polymerase, an enzyme involved in DNA replication. Additionally, enzymes like lipase and protease function intracellularly in breaking down lipid and protein molecules, respectively.
What are examples of enzymes in living things?
Examples of enzymes in living things include amylase (breaks down carbohydrates), catalase (converts hydrogen peroxide into water and oxygen), and DNA polymerase (involved in DNA replication). These enzymes play crucial roles in various biological processes such as digestion, metabolism, and genetic replication.
What is the function of proofreader enzymes?
Proofreader enzymes, such as DNA polymerases, function to detect and correct errors that may occur during DNA replication. They help maintain the accuracy of genetic information by identifying mismatched base pairs and replacing them with the correct ones. This process helps prevent mutations and ensures the fidelity of DNA replication.
The best objective to describe DNA replication is?
The best objective to describe DNA replication is to understand the process by which a cell makes an identical copy of its DNA. This includes grasping the role of enzymes like DNA polymerase, the significance of semi-conservative replication, and the importance of fidelity to maintain genetic information.
DNA polymerase and helicase are alike how?
Both DNA polymerase and helicase are enzymes involved in DNA replication. While DNA polymerase adds nucleotides to the growing DNA strand during replication, helicase unwinds the double-stranded DNA to facilitate replication. Both enzymes are essential for the accurate and efficient duplication of the genetic material.
Why DNA replication is popularly known as enzyme dependent?
DNA replication is aided by enzymes. Without the enzymes DNA will not be able to replicate.There are three main enzymes involved-Helicase - This enzyme separates the two parental DNADNA Polymerase - This enzyme exists in different forms and each one of them have a specific function in the replication of DNA.In short, it enhances each strands, adds base pairs and repairs any damage done to the strands during the replication process.Ligase - This enzyme puts the two stands together after the replication is complete.

What are the chemical reactions in which enzymes are involved?
Enzymes are involved in a wide variety of chemical reactions in living organisms, including breaking down food molecules into energy (such as in digestion), building new molecules (such as DNA replication), and facilitating cellular processes (such as metabolism). Enzymes function by lowering the activation energy required for a reaction to occur, thereby increasing the rate of the reaction without being consumed themselves.
Inhibitors of DNA replication?
Inhibitors of DNA replication include drugs like Ciprofloxacin and Doxorubicin, which interfere with the enzymes involved in DNA synthesis. These inhibitors disrupt the process of replication by blocking DNA polymerase or topoisomerase enzymes, preventing proper DNA synthesis and cell division. This can be used in cancer therapy to inhibit cell proliferation.
What is the function of the single strand binding protein in DNA replication?
The single strand binding protein in DNA replication helps to stabilize and protect the single-stranded DNA during the replication process, preventing it from forming secondary structures and allowing enzymes to access the DNA for replication.
DNA replication occurs with or without the aid of enzymes?
DNA replication requires the aid of enzymes. Enzymes like DNA polymerase and helicase are crucial for unwinding the DNA double helix, synthesizing new DNA strands, and proofreading and repairing any errors that may occur during replication. Without these enzymes, DNA replication cannot proceed effectively and accurately.
What enhances separation of DNA strands during replication?
Helicase enzymes are responsible for unwinding and separating the DNA strands during replication by breaking the hydrogen bonds between the bases. This creates the replication fork where new nucleotides can be added by DNA polymerase enzymes. ATP provides the energy needed for helicase to perform its unwinding function.
What is the function of proofreader enzymes?
Proofreader enzymes, such as DNA polymerases, function to detect and correct errors that may occur during DNA replication. They help maintain the accuracy of genetic information by identifying mismatched base pairs and replacing them with the correct ones. This process helps prevent mutations and ensures the fidelity of DNA replication.
What is DNA replication is performed by?
DNA replication is performed by a group of enzymes known as DNA polymerases. These enzymes are responsible for synthesizing new DNA strands by adding nucleotides in a complementary fashion to the existing DNA template. Other proteins are also involved in DNA replication to help unwind the double helix, stabilize the replication fork, and proofread the newly synthesized DNA.
How does the ssb protein facilitate and regulate the process of DNA replication?
The ssb protein helps in DNA replication by binding to single-stranded DNA, protecting it from damage and preventing it from forming secondary structures. This allows other proteins involved in replication to access the DNA and carry out the process efficiently. Additionally, ssb protein helps regulate the replication process by interacting with other proteins and enzymes involved in DNA replication, ensuring that it occurs accurately and in a coordinated manner.
How do single strand binding proteins contribute to the process of DNA replication?
Single strand binding proteins stabilize the unwound DNA strands during replication by preventing them from re-forming into a double helix. This allows other enzymes and proteins involved in replication to access the single-stranded DNA and carry out the replication process efficiently.
