The nucleoid occlusion mechanism is critical for the timing of chromosome partitioning. This mechanism ensures that . A. the Z ring forms before chromosome segregation B. the Z ring forms after the cell wall synthesizing machinery is assembled C. the Z ring forms after chromosome segregation D. the Z ring forms after the divisome is assembled

C. The Z ring forms after chromosome segregation

Explanation:

Nucleoid occlusion, NO, is a mechanism in which the nucleoid prevents the the division of the chromosome in the cell's cylindrical part before segregation of the chromosome around the middle of the cell

NO is achieved by not allowing the formation of Z ring formation close to the nucleoid, (before the chromosome is segregated) thereby aiding the specification of the septation location

Therefore, the Z ring is formed after the chromosome is segregated

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands
