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 is enzyme that adds nucleotides to exposed nitrogen bases?
DNA polymerase is the enzyme that adds complementary nucleotides to exposed nitrogen bases during DNA replication.
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.
Which mechanism(s) operate(s) to ensure the accuracy of DNA replication?
DNA replication accuracy is ensured primarily through three mechanisms: base pairing fidelity, proofreading by DNA polymerases, and mismatch repair. During replication, DNA polymerases incorporate nucleotides based on complementary base pairing, minimizing errors. Additionally, many DNA polymerases possess a proofreading ability, allowing them to remove incorrectly paired nucleotides immediately after they are added. Finally, if any mismatches persist, the mismatch repair system detects and corrects these errors post-replication, maintaining genomic integrity.
What class of enzyme is DNA polymerase?
DNA polymerase is a catalyst, by catalyzing the synthesis of new DNA by adding nucleotides to a preexisting chain. There are several different DNA polymerases, but DNA polymerase I and DNA polymerase II play the major roles in DNA replication.

Enzymes that move along each of the DNA strands during replication adding nucleotides to the exposed bases of what?
Enzymes such as DNA polymerase move along each DNA strand during replication, adding complementary nucleotides to the exposed bases of the template strand. This process ensures the accurate replication of the genetic information from one generation to the next.
What is enzyme that adds nucleotides to exposed nitrogen bases?
DNA polymerase is the enzyme that adds complementary nucleotides to exposed nitrogen bases during DNA replication.
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 pairs with adenine during DNA replication?
DNA polymerases add nucleotides to the exposed base pairs according to base-pairing rules.
What are the two major functions that DNA polymerase performs?
DNA polymerase functions to catalyze the synthesis of new DNA strands by adding nucleotides to a growing DNA chain during replication. It also can recognize and correct errors in the newly synthesized DNA through its proofreading activity.
How does DNA go from 3' to 5' during the process of replication?
During DNA replication, the new strand is synthesized in the 5' to 3' direction. The original DNA strand is read in the 3' to 5' direction, and the new strand is built by adding nucleotides in the 5' to 3' direction. This process is carried out by enzymes called DNA polymerases.
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.
How does DNA polymerase add nucleotides during the process of DNA replication?
DNA polymerase adds nucleotides during DNA replication by recognizing the complementary base pairs on the template strand and adding corresponding nucleotides to the growing new strand. This process ensures accurate replication of the genetic information.
How are proteins involved in the process of DNA replication?
During DNA replication, proteins called DNA polymerases help to copy the DNA strands by adding new nucleotides to the existing strands. Other proteins, like helicases and topoisomerases, unwind and stabilize the DNA strands to allow for replication to occur smoothly. Proteins also help in proofreading and repairing any mistakes that may occur during the replication process.
What are enzymes that have a proofreading role in DNA replication?
DNA polymerases, such as DNA polymerase III in prokaryotes and DNA polymerase delta in eukaryotes, have proofreading activities during DNA replication. These enzymes possess exonuclease activity, allowing them to detect and correct errors in newly synthesized DNA strands by removing misincorporated nucleotides. This proofreading function helps maintain the fidelity of DNA replication.
