Upon a double-stranded DNA break, a cell can repair the DNA by resecting damaged DNA by nucleases and resynthesis of DNA by DNA polymerase. Next, DNA ligase binds the resynthesized fragment to the original DNA strand. What best describes this process?

The correct answer is non-homologous end joining repair. This type of DNA repair is more common than homology-directed repair which repairs damaged DNA by using a homologous template. Homologous recombination is a specific type of homology-directed repair. V(D)J recombination is a form of genetic recombination that occurs in developing lymphocytes to give rise to diverse antibodies. Selective autophagy is the selective removal of damaged proteins from the cell following a stress event such as heat exposure.

DNA ligase IV has been studied for its role in what process specifically?
DNA ligase IV has been studied for its role in what process specifically?
The correct answer is non-homologous end joining DNA repair. This specific DNA ligase joins the double stranded phosphodiester bond break in DNA by consumption of ATP, however, this repair mechanism often times is error prone and results in indels (insertion/deletion mutations). Homology directed DNA repair and homologous recombination are very similar processes that rely on template sequences to "swap" DNA sequences with other parts of the genome, however, they do not rely on this ligase. DNA ligase IV does not have a role in DNA replication.
