The main enzymes involved in DNA replication are:
Helicase: unwinds the double helix into two strands
Polymerase: adds nucleotides to an existing strand
Ligase: brings together the Okazaki fragments
Topoisomerase: cuts and rejoins the helix
RNA primase: catalyzes the synthesis of RNA primers
Hope this helps!

What enzymes produced a new DNA strand during DNA replication?
DNA Polymerase
What 2 enzymes are during DNA replication Describe what each does during replication?
During DNA replication, two key enzymes are DNA helicase and DNA polymerase. DNA helicase unwinds and separates the double-stranded DNA, creating two single strands that serve as templates for replication. DNA polymerase then synthesizes new DNA strands by adding nucleotides complementary to the template strands, effectively elongating the newly formed DNA. Together, these enzymes ensure accurate and efficient replication of the genetic material.
Is DNA oxidase responsible for replication of DNA?
No, at least not on its own. There are at least 32 (there may be more undiscovered that have more minor rolls in the process) different enzymes that are part of the DNA replication process. For example, DNA helicase "unzips" the DNA strand. There are also enzymes that prime it, copy, fix errors, etc.
Explain the two roles that enzymes play in DNA replication as is illustared infigure 9 in this section?
an enzyme called DNA helicases unwinds the double helix before DNA replication begins. enzymes known as DNA polymerases move along each of tge DNA strands while adding nucleotides to the exposed nitrogen bases according to the base pairing rules.
What catalyzes DNA synthesis?
DNA synthesis is catalyzed by enzymes called DNA polymerases. These enzymes are responsible for assembling new DNA strands by adding nucleotides to the growing chain during DNA 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.

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.
How do enzymes explain how they do the actual work of replication?
Enzymes play a crucial role in the process of DNA replication by facilitating the unwinding of the DNA double helix, the synthesis of new DNA strands, and the proofreading of the newly synthesized DNA. Enzymes such as helicase unwind the DNA strands, DNA polymerase adds new nucleotides to the growing DNA strand, and exonuclease proofreads and corrects any errors. Overall, enzymes help to ensure that DNA replication is accurate and efficient.
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.
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.
Why are enzymes important to the DNA replication?
Enzymes are essential for DNA replication because they facilitate the unwinding of the DNA double helix, the synthesis of new complementary strands, and the proofreading and repair of any errors that occur during replication. They also help regulate the process to ensure accurate and efficient copying of the genetic material.
What controls DNA replication?
DNA replication is controlled by specific enzymes, such as DNA polymerase, helicase, and primase, along with other regulatory proteins. The process is tightly regulated at different checkpoints to ensure accurate copying of the genetic material. Additionally, the initiation of DNA replication requires specific sequences called origins of replication.
What is it called when DNA separate into two strands?
DNA Replication by enzymes that copy DNA for chromosomes in the new cell after cell division (mitosis)
What happenes first at each origin of replication?
Enzymes unwind DNA!
How do replication bubbles form during the process of DNA replication?
During DNA replication, replication bubbles form when the DNA double helix unwinds and separates into two strands. Enzymes called helicases unwind the DNA, creating a replication fork where new DNA strands can be synthesized. This process allows for multiple replication bubbles to form along the DNA molecule, enabling efficient and accurate replication.
