Question

re-write this in a 9th grade level:

During binary fission in bacteria, the circular chromosome with regions called the origin and terminus of replication is copied as the cell elongates. The origins move towards opposite ends, leading to the formation of a septum that divides the cell into two new cells. As the membrane pinches inward, a new cell wall forms, eventually splitting to release two new bacteria. This process allows for the efficient replication and division of bacterial cells.

Answer 1

In bacteria, binary fission is a process where the circular chromosome is duplicated as the cell gets longer. The parts of the chromosome that help with replication, called the origin and terminus, are important in this process. The duplication causes two copies of the chromosome to move to opposite sides of the cell. This movement creates a barrier in the middle of the cell, called the septum, which divides the cell into two. As the cell membrane moves in, a new cell wall forms, creating two separate bacteria. This method helps bacteria quickly make copies of themselves.
