What is the difference between DNA polymerase I II and III?
DNA polymerase I, II, and III are enzymes involved in DNA replication in prokaryotes. DNA polymerase I is responsible for removing RNA primers during DNA replication and filling the gaps with DNA nucleotides. DNA polymerase II is involved in DNA repair pathways, particularly in response to DNA damage. DNA polymerase III is the main enzyme responsible for synthesizing a new DNA strand during replication. It has a high processivity and is the primary enzyme involved in synthesizing the leading and lagging strands of DNA.
What is the name of the two enzymes that help in the duplication of DNA?
More than two enzymes are involved. However, the main ones are DNA Polymerase I and DNA Polymerase III. DNA Polymerase III adds new nucleotides and DNA Polymerase I removes primers.
What chemical is an enzyme that add nucleotides to a new strand of DNA during replication?
DNA Polymerase is the enzyme which adds new nucleotides during replication.
Which enzyme is responsible for facilitating the hydrogen bonding between nucleotides in a new molecule?
the DNA polymerase III
What specific component does DNA polymerase III require in order to function correctly?
DNA polymerase III requires a primer, which is a short piece of RNA or DNA, in order to function correctly.
What enzyme transcribes DNA?
The enzyme that transcribes the DNA into RNA is called RNA polymerase.
What enzyme elongates DNA?
DNA polymerase is the main enzyme responsible for elongating DNA strands during DNA replication. It catalyzes the addition of nucleotides to the growing strand in a 5' to 3' direction.
How does DNA polymerase III add nucleotides during the process of DNA replication?
DNA polymerase III adds nucleotides during DNA replication by attaching them to the growing DNA strand in a specific order that matches the complementary bases on the template strand. This enzyme catalyzes the formation of phosphodiester bonds between the nucleotides, creating a new strand of DNA that is identical to the original template strand.
The enzyme that attaches nucleotides thgether by forming phosphdiester bonds between sugar and phosphate molecules during DNA repliccation is known as?
DNA polymerase is the enzyme responsible for attaching nucleotides together by forming phosphodiester bonds during DNA replication.
Which enzyme is used in the synthesis of new copies of DNA?
In humans, many enzymes are involved in DNA replication. Among them are: DNA polymerase I DNA polymerase III Ligase Primase Helicase DNA polymerase I and III perform the bulk of the actual reproduction--their job is to add nucleotides to the growing strands. The others perform specialized functions and are essential to the process.
What are the four enzymes involved in DNA replication and repair?
The four enzymes involved in DNA replication and repair are DNA polymerase, DNA helicase, DNA ligase, and DNA primase. DNA polymerase synthesizes new DNA strands, DNA helicase unwinds the double helix, DNA ligase joins the Okazaki fragments on the lagging strand, and DNA primase synthesizes RNA primers for DNA polymerase to begin replication.
What enzyme attaches and adds the matching nucleotides?
DNA Polymerase III adds nucleotides during DNA replication. DNA Polymerase I also adds nucleotides (to a lesser extent). DNA Pol I is responsible for replacing the primers with dNTPs, these sections are then joined to the rest by DNA Ligase.
