DNA ligase is used to form "glue" fragments of DNA together in order to form new DNA strands during DNA replication. It does so by forming phosphodiester bonds between DNA monomers.What is DNA Ligase? Deoxyribonucleic acid (DNA) is a double-stranded molecule found in the nucleus of eukaryotic...
DNA ligase In the cell, the function of DNA ligase is to covalently link the fragments of the lagging strand during DNA replication, or to repair single-stranded breaks (“discontinuities”) that arise in double-stranded DNA molecules during DNA replication or during DNA damage repair. DNA liga...

DNA ligase 1 finalizes nuclear DNA replication by accurately sealing nicks generated during Okazaki Fragment Maturation. Here, Williams et al employ a low fidelity DNA ligase 1 variant to study mutation rates and specificity across the yeast genome ...
Identify the function of the protein: DNA ligase. Describe the structure and function of DNA. What is the function of DNA ligase in DNA replication? Describe the function of DNA polymerase I in leading strand synthesis in DNA synthesis. Describe the function of DNA polymerase I in opening the...
What is the function of topoisomerase in DNA replication? What role does DNA play in protein synthesis? What is the purpose of DNA sequencing? How does DNA ligase work? What is the primary function of DNA? What is the purpose of DNA replication in DNA structure?
, instead of a DNA polymerase as in bacteria, removes the RNA primer, which is then replaced with DNA nucleotides. The gaps that remain are sealed byDNA ligase. Because eukaryotic chromosomes are linear, one might expect that their replication would be more straightforward. As in prokaryotes, ...
