How is DNA separated into daughter cells during bacterial binary fission? Microtubules attach and pull chromosomes apart. Mitochondria supply energy for active chromosome movement. Nuclear envelope breaks down, allowing chromosomes to separate. The two chromosomes are pulled apart as the cell elongates. They just rely on chance. If a cell doesn’t get a chromosome, it dies. The other one divides again.

When bacteria divide, how do their chromosomes split into new cells? Centrosomes bind to the kinetochore and pull them apart. The bacterial centromere binds to both ends of the dividing cell. Each chromosome binds to the inner bacterial membrane at one location, which then splits. The chromosomes entirely bind to the inner membrane, which splits. Microtubules form at each end of the cell to pull the chromosomes apart.

In bacteria: a. several chromosomes undergo mitosis. b. binary fission produces four daughter cells. c. replication begins at the origin, and the DNA strands separate. d. the plasma membrane plays an important role in separating the duplicated chromosomes into the two daughter cells. the daughter cells receive different genetic information from the parent cell.
