Binary fission in bacteria differs from mitosis because
A) the chromosome copies attach to the plasma membrane and are pulled apart by cell growth.
B) the chromosome is a simple DNA strand without complex proteins and no spindle forms.
C) there is no nuclear membrane to break down and rebuild.
D) All of the choices are correct.
E) None of the choices are correct.

Question

Quizplus · Accepted Answer

Binary fission in bacteria differs from mitosis in multiple ways. Firstly, the chromosome in bacterial binary fission is a simple, circular DNA strand without histones or other complex proteins, unlike the linear, histone-bound chromosomes in eukaryotic mitosis. Secondly, there is no nuclear membrane to break down and rebuild in bacterial binary fission. Finally, in bacterial binary fission, the chromosome copies attach to the plasma membrane and are pulled apart by cell growth, while in mitosis, the spindle apparatus is responsible for separating the chromosomes. Therefore, all of the choices listed in option D are correct.
