What is the principle enzyme involved in DNA replication?
Two of the enzymes involved in DNA replication are helicase and DNA polymerase. Helicase unwinds the DNA strand and DNA polymerase makes a copy.
What are the 4 enzymes in DNA replication?
DNA Helicase - responsible for separating the two stands DNA Polymerase - responsible for catalyzing the addition of bases to the new strand DNA Ligase - responsible for sealing fragments
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 separates the DNA strands during replication?
During replication, enzymes called helicases unwind and separate the DNA strands by breaking the hydrogen bonds between the base pairs. This process creates a replication fork where new complementary strands are synthesized.
What role does the enzyme helicase play in the process of DNA replication?
Helicase is an enzyme that unwinds the double-stranded DNA molecule during replication by breaking the hydrogen bonds between the base pairs. This allows the DNA polymerase enzyme to access the separated strands and synthesize new complementary strands. In essence, helicase plays a crucial role in the initiation of DNA replication by separating the two strands of the DNA double helix.
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.

What is the difference between the Helicase and DNA polymerase enzme?
The helicase in a way unzipps the wound DNA. DNA Polymerase then matches the nucleotide bases with free floating one so that A matches with T (or in RNA U) and G matches with C. Creating two new strands of DNA and completing DNA replication.
What separates the DNA strands during replication?
During replication, enzymes called helicases unwind and separate the DNA strands by breaking the hydrogen bonds between the base pairs. This process creates a replication fork where new complementary strands are synthesized.

This allows the DNA polymerase enzyme to access the separated strands and synthesize new complementary strands. In essence, helicase plays a crucial role in the initiation of DNA replication by separating the two strands of the DNA double helix.
What enzyme is responsible for unwinding the DNA molecule for replication?
The enzyme responsible for unwinding the DNA molecule for replication is called helicase. Helicase breaks the hydrogen bonds between the DNA base pairs, allowing the two strands to separate and expose the nucleotide bases for replication.
Which is the function of the DNA helicase enzyme in the DNA replication process?
DNA helicase is responsible for unwinding the double-stranded DNA during DNA replication. It separates the two strands of DNA by breaking the hydrogen bonds between the base pairs, allowing DNA polymerase to access the template strand and synthesize a new complementary strand.
What is the difference between the helicase enzyme and DNA polymerase enzyme?
Helicase splits the 3' and 5' Okazaki fragments, while the DNA polymerase attaches the "new" 3' nucleotide, with the "old" 5' nucleotide. As well as proofreading, or making sure that the bases are complementary in order to avoid mutations.
What is the enzyme that unwinds DNA prior to replication?
The enzyme that unwinds DNA prior to replication is called helicase. Helicase plays a crucial role in DNA replication by breaking the hydrogen bonds between the base pairs of the double-stranded DNA molecule, allowing the two strands to separate and form the replication fork. This process is essential for the replication of DNA during cell division and ensures that the genetic information is accurately copied.
What enzyme breaks hydrogen bonds between nitrogen bases?
Helicase and RNA polymerase separate DNA strands by breaking the hydrogen bonds between complementary bases.Helicase parts the strands of DNA during DNA replication, and RNA polymerase parts them during transcription.The enzyme that separates DNA in called DNA helicases. There are two of them that work away from the origin of replication, creating in "bubble" in the DNA molecule. For eukaryotes, there would be several origins of replication but in prokaryotes, there is only one origin of replication.
