We found that Xrcc4--ligase IV is not required for but rather suppresses translocations In addition to Xrcc4--ligase IV, mammalian cells have 2 more ATP-dependent DNA ligases, DNA ligase I and DNA ligase III, which are required for DNA replication and repair. Ligase III is also implicated...
The activity of DNA ligase is observed in the lagging strand or the Okazaki fragment. Due to the presences of nicks or gaps in the lagging strand, the... Learn more about this topic: DNA Ligase | Definition, Function & Role from

A nucleosome is a fundamental unit of chromatin composed of 147 base pairs of DNA and an octamer of core histone proteins, two copies each of histones H2A, H2B, H3, and H4. Histone proteins are basic and conserved from archaea to humans based on the amino acid sequence.29,30Histone underg...
Despite the volume of research on RIPKs and host responses to infection, there is a long way to go in understanding the physiological role of each RIPK and their functional domains in specific infection settings. This is partly due the fact that RIPK1 and RIPK3 are implicated in pro-...
Additionally, a DNA ligaseIV-dependent pathway was proposed [25]. Function: SpcDNA is a common element in a large variety of eukaryotic cells, but its quantity is limited [22]. It is much more abundant in genetically unstable cells and tissues, such as HeLa cells, colon carcinoma, ...
II. Foreign DNA and plasmids are mixed together III. DNA ligase is used to seal the nicks in the sugar–phosphate backbone. IV. Cut the foreign DNA (containing the DNA fragment of interest) and the plasmid with the same restriction enzyme. View Solution Q4...
Describe the role of DNA polymerase: DNA Replication:DNA replication is the process that leads to the copying of a cell's genome. This process is carried out by a series of enzymes that prepare the DNA molecule for replication and then carry out the steps of primer binding, elongation and ...
