See the article on restriction enzymes and DNA ligase for a more concrete example of how and why these different ligation products can form.
Overview: DNA cloning (article) | Khan Academy
A restriction enzyme is a DNA-cutting enzyme that recognizes a specific target sequence and cuts DNA into two pieces at or near that site. Many restriction enzymes produce cut ends with short, single …
