How do eukaryotic cells divide by binary fission?

Answer 1

Binary fission, or prokaryotic fission, is the form of asexual reproduction and cell division used by all prokaryotes, some protozoa, and some organelles within eukaryotic organisms. This process results in the reproduction of a living prokaryotic cell by division into two parts which each have the potential to grow to the size of the original cell.

Mitosis and cytokinesis are not the same as binary fission; specifically, binary fission cannot be divided into prophase, metaphase, anaphase, and telophase because prokaryotes have no nucleus and no centromeres. The ability of some multicellular animals, such as echinoderms and flatworms, to regenerate two whole organisms after having been cut in half, is also not the same as binary fission. Neither is vegetative reproduction of plants.

Binary fission begins with DNA replication. DNA replication starts from an origin of replication, which opens up into a replication bubble (note: prokaryotic DNA replication usually has only 1 origin of replication, whereas eukaryotes have multiple origins of replication). The replication bubble separates the DNA double strand, each strand acts as template for synthesis of a daughter strand by semiconservative replication, until the entire prokaryotic DNA is duplicated.

After this replicational process, cell growth occurs.

Each circular DNA strand then attaches to the cell membrane. The cell elongates, causing the two chromosomes to separate.

Cell division in bacteria is controlled by the FtsZ, a collection of about a dozen proteins that collect around the site of division. There, they direct assembly of the division septum. The cell wall and plasma membrane starts growing transversely from near the middle of the dividing cell. This separates the parent cell into two nearly equal daughter cells, each having a nuclear body.[1]

The cell membrane then invaginates (grows inwards) and splits the cell into two daughter cells, separated by a newly grown cell plate.

Use by eukaryotic organelles

Eukaryotic organelles such as mitochondria, chloroplasts, and peroxisomes also reproduce within the eukaryotic cell by binary fission. How they are allotted to one descendant cell or the other during mitosis and cytokinesis is not yet clear

Answer 2

Yes, prokaryotic cells divide by a process called binary fission. The cell first makes a replicate of its DNA then splits itself into two cells. Since the DNA is the same in both cells they are genetically identical.

Answer 3

Prokaryotic cell differ from eukaryotic cell in that they lack a nucleus and membranous organells.Now the main feautures inside a prokaryotic cell are:

1)Cytoplasm

2)Ribosomes

3)Plasmid

4)Nucleoid(circular DNA)

And feautures outside the prokaryotic cell are:

1)Capsule

2)Pili(hair like structures on surface of capsule)

3)Flagellum(tail like structure)

Answer 4

First the chromosomes replicate: then The nucleus disappears: then the chromosomes go to the middle of the cells: then one set of replicas goes to one side cell and another set of replicas goes to the other side of the cell: then the cell splits and evenly spills the organelles and cytoplasm into each cell in the process

Answer 5

Bacteria reproduce by type of cell division called binary fission which is a form of asexual reproduction that produces identical offspring.

Answer 6

Prokaryotic cells divide using binary fission, an asexual process of reproduction. The process starts with a single molecule that replicates and becomes two identical cells.

Answer 7

Prokaryotic cells can divide in a number of ways. They can divide using meiosis, mitosis or binary fission which are all ways to reproduce.
