Question

Which eukaryotic cell-cycle event is missing in binary fission?

a) S phase
b) G1 phase
c) G2 phase
d) M phase

Answer 1

Binary fission does not involve the eukaryotic cell-cycle events of G1 phase, S phase, G2 phase, and M phase.

Step-by-step explanation:

Binary fission is a form of cell division that occurs in prokaryotic cells, such as bacteria. Unlike the eukaryotic cell cycle, binary fission does not involve distinct phases like G1, S, G2, and M phases. Instead, it is a simple process where the cell grows in size, duplicates its DNA, and then divides into two daughter cells. Therefore, the eukaryotic cell-cycle events of G1 phase, S phase, G2 phase, and M phase are all missing in binary fission.
