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.

Sticky ends are produced as a result of the action of?
restriction enzymes on DNA molecules.
What enzyme binds fragments of DNA on the lagging strand?
DNA ligase is the enzyme that binds together the Okazaki fragments on the lagging strand during DNA replication. It forms phosphodiester bonds between adjacent nucleotides to create a continuous strand of DNA.
WHAT IS The role of peg in ligation buffer?
Polyethylene glycol (PEG) in ligation buffer is used to promote the binding of DNA fragments by decreasing electrostatic repulsion between them. PEG helps to increase the efficiency of ligation reactions by bringing DNA fragments closer together and facilitating their joining by DNA ligase.
Which enzyme do scientists use to bond a new gene to plasmid DNA?
Scientists use DNA ligase to bond a new gene to plasmid DNA. DNA ligase catalyzes the formation of phosphodiester bonds between the ends of the new gene and the plasmid, creating a recombinant 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.
Sticky ends are produced as a result of the action of?
restriction enzymes on DNA molecules.
What enzyme joins pieces of DNA together?
Ligase is used to join DNA strands together
What enzyme binds fragments of DNA on the lagging strand?
DNA ligase is the enzyme that binds together the Okazaki fragments on the lagging strand during DNA replication. It forms phosphodiester bonds between adjacent nucleotides to create a continuous strand of DNA.
What DNA replication enzyme attaches okazaki fragments as a continuous strand of DNA?
DNA ligase is the enzyme responsible for joining together the Okazaki fragments on the lagging strand to create a continuous strand of DNA during DNA replication.

Scientists use DNA ligase to bond a new gene to plasmid DNA. DNA ligase catalyzes the formation of phosphodiester bonds between the ends of the new gene and the plasmid, creating a recombinant DNA molecule.
What is DNA ligase functions?
Ligase joins together the Okazaki fragments into a continuous strand of DNA.
What is the function of DNA ligase?
Ligase joins together the Okazaki fragments into a continuous strand of DNA.
Name the enzyme joining Okazaki fragments?
DNA ligase is the enzyme that is responsible for joining Okazaki fragments on the lagging strand during DNA replication. It catalyzes the formation of phosphodiester bonds between the fragments, sealing the gaps in the newly synthesized DNA.
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.
Do people with xeroderma pigmentosa have DNA ligase?
Yes, people with xeroderma pigmentosa have DNA ligase. DNA ligase is an enzyme involved in the repair of DNA damage, which is particularly important for individuals with xeroderma pigmentosa who have a reduced ability to repair damage caused by ultraviolet (UV) radiation.
Which pair of enzymes is necessary to make recombinant DNA?
Restriction enzymes and DNA ligase are necessary to make recombinant DNA. Restriction enzymes are used to cut the DNA at specific sequences, while DNA ligase is used to join together pieces of DNA from different sources.
