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 enzyme builds new DNA strands from existing strands during DNA replication?
DNA Polymerase III is responsible for adding new nucleotides to the strand being synthesised. Also involved in DNA replication are DNA Polymerase I which replaces primers with nucleotides, and DNA Ligase which joins fragments of DNA together.
Do enzymes unwind the two strands of the parent DNA double helix during DNA replication?
Several enzymes participate in DNA replication, one being helicase which unwinds the two nucleotide strands.Binding proteins stabilize the single stranded DNA and DNA polymerase attach the free nucleotides to the growing strand. The DNA ligases seal the short stretches of nucleotides into one continuous strand
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 happens first at each origin replication?
Enzymes unwind DNA!
Enzymes that move along each of the DNA strands during replication adding nucleotides to the exposed bases?
DNA polymerases
How many strands are there at the beginning of DNA replication?
At the beginning of DNA replication there are two strands of DNA nucleotides.
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 are the enzymes that are responisble for adding nucleotides to the exposed DNA bases during replication?
The enzymes responsible for adding nucleotides to the exposed DNA bases during replication are DNA polymerases. These enzymes catalyze the formation of phosphodiester bonds between adjacent nucleotides in the growing DNA strand based on the complementary base-pairing rule. Multiple types of DNA polymerases work together during DNA replication to ensure accurate and efficient synthesis of the new DNA strands.

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.
What unzips DNA so it can duplicate?
Enzymes called helicases are responsible for unzipping the DNA double helix so that it can be duplicated. Helicases break the hydrogen bonds between the paired nucleotides of the DNA strands, allowing the strands to separate and serve as templates for the synthesis of new DNA strands during replication.
The enzyme that adds new nucleotides to each side of a replicating DNA molecule is?
DNA polymerase is the enzyme that adds new nucleotides to each side of a replicating DNA molecule. It catalyzes the synthesis of new DNA strands by adding complementary nucleotides to the existing template strands during DNA replication.
