What is the function of the enzyme DNA ligase?
DNA ligase is an enzyme that plays a crucial role in the process of DNA replication and repair by joining together the ends of DNA strands to form a continuous strand.
How does DNA ligase utilize ATP during the process of DNA repair and replication?
DNA ligase utilizes ATP during the process of DNA repair and replication by using the energy from ATP to catalyze the formation of a phosphodiester bond between the DNA strands, sealing any breaks or gaps in the DNA molecule.
What is the mechanism of DNA ligase in the process of DNA replication and repair?
DNA ligase is an enzyme that plays a crucial role in the process of DNA replication and repair by joining together the ends of DNA strands. It forms a bond between the sugar-phosphate backbone of adjacent DNA fragments, sealing any breaks or gaps in the DNA molecule. This helps to ensure the integrity and stability of the DNA molecule during replication and repair processes.
What type of biology do DNA ligase belong to?
DNA ligase belongs to the field of molecular biology, specifically enzyme biology. It plays a crucial role in the process of DNA replication and repair by catalyzing the formation of phosphodiester bonds between DNA strands.
How does ligase work to join DNA fragments together?
Ligase is an enzyme that helps to join DNA fragments together by forming a strong bond between the sugar-phosphate backbone of the DNA strands. This process is essential for DNA replication, repair, and recombination.

What is the enzyme that connects the okasaki fragments and participates in DNA repair?
The enzyme that connects Okazaki fragments during DNA replication is DNA ligase. DNA ligase is also involved in repairing nicks in the sugar-phosphate backbone of DNA during processes such as base excision repair and mismatch repair.
Short segments of newly synthesized DNA are joined into a continuous strand by?
ligase enzymes, which catalyze the formation of phosphodiester bonds between adjacent DNA fragments. This process is crucial for the completion of DNA replication and repair, as well as for the creation of recombinant DNA molecules in genetic engineering techniques.
What is the mechanism of action of DNA ligase in a DNA ligase reaction?
DNA ligase is an enzyme that plays a crucial role in the process of DNA replication and repair by joining together the ends of DNA strands. It works by forming a phosphodiester bond between the phosphate group of one DNA strand and the hydroxyl group of another, effectively sealing the break in the DNA backbone. This process helps to ensure the integrity and stability of the DNA molecule.
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 are the properties of a ligase?
Ligases are enzymes that catalyze the joining of two molecules by forming a phosphodiester bond. They require ATP as a cofactor to drive the reaction. Ligases play a key role in DNA replication, repair, and recombination processes.
The primary function of DNA ligase is to?
The primary function of DNA ligase is to reassemble DNA fragments produced by the use of restriction enzymes. The pieces are joined using a process called ligation, which uses the enzyme, DNA ligase which acts as a molecular 'stapler'. The fragments are joined as follows: - sticky-ended DNA fragments are created from two DNA sources using the same restriction enzyme. - The DNA from the two sources is mixed and complementary ends allowed to form complementary base pairs. This process forming loose and temporary join by hydrogen bonding is called annealing. - DNA ligase is then added to form a permanent link.
