Answer 1

The correct order of steps in bacterial replication, starting from a parent cell, is: Chromosome replication, Cell elongation, Septum formation, Separation of daughter cells.

Step-by-step explanation:

The correct order of steps in bacterial replication, starting from a parent cell, is:

1. Chromosome replication
2. Cell elongation
3. Septum formation
4. Separation of daughter cells

After the origin of replication on the circular chromosome, DNA replication occurs in opposite directions until the terminus is reached. As the new strands form, the origin points move away from the cell wall attachment, the cell elongates, and the growing membrane aids in the transport of the chromosomes. The formation of a ring composed of FtsZ triggers the accumulation of proteins for septum formation, and when the new cell walls are in place, the daughter cells separate.
