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?

DNA ligase IV has been studied for its role in what process specifically?

Primase is an enzyme that synthesize small primers for DNA polymerase to bind to so it can initiate DNA replication. What are these primers made of?
