Answer

The binucleate condition of liver cells can be explained via the process of amitosis, which unlike mitosis, occurs in the absence of a spindle fiber complex which commonly separates the nucleus into two new nuclei. As spindle fibers are not present during amitosis, successful separation of the nucleus is not guaranteed in amitosis, and thus daughter cells are more likely to have two nuclei. This results in binucleated cells being more common in the liver.
