In binary fission, the DNA from the parent cell first undergoes replication. This means that the DNA makes an identical copy of itself. Replication occurs as the DNA strands separate and new complementary strands are synthesized based on the original strands. This results in two complete copies of the DNA molecule, each consisting of one original strand and one newly synthesized strand.
After the DNA has replicated, it begins to coil up. This coiling is a process called supercoiling, which allows the DNA to condense and fit within the cell. The coiled DNA is then ready to be distributed to the daughter cells.
Once the DNA is properly coiled, it moves toward one pole of the parent cell. The pole is a specific region of the cell where the DNA will eventually be separated into the two new daughter cells. The movement of the DNA is facilitated by proteins and molecular machinery within the cell, which help guide the DNA to the appropriate location.
Finally, after the DNA has reached one pole of the parent cell, the process of cell division occurs. The parent cell membrane intes and eventually splits into two, resulting in the formation of two daughter cells. Each daughter cell receives a copy of the coiled and replicated DNA, along with other cellular components like cytoplasm, which are also evenly distributed between the two cells.
So, in summary, in binary fission, the DNA from the parent cell first replicates, then coils up, moves toward one pole, and finally produces daughter cells.
