The question should have been more clearer than that. Like I don't understand why can't you just make the question better format than that. Like seriously I was confused because it asked us what enzyme is that look at the red part. Like who would understand that even. Seriously is it really that hard to make it simple. I am just so confused.

Ligase is the enzyme that will fix this lagging strand. When DNA is replicated for cell division, only one of the strands can be replicated in one continuous strand. The other half of the DNA is replicated in short spurts. This short spurt results in the kind of thing seen in the picture. The ligase binds the short, lagging pieces. The ligase will also fix any missing pieces in a DNA strand so long as it has a template to work with. However, there’s also a kind of ligase that’ll fix a break occurring in both strands of DNA at the same place.

In non-technical terms, a ligase will make the same kind of phosphorous base that is used to make the backbone of the DNA chain. In short, that’s how it binds the DNA.

Without why. That's the answer but I just wish that the question was much clearer and the diagram was better than that
