Which cells divide by construction of a ring of protein?
Cells that divide by constructing a ring of protein typically include bacterial and archaeal cells. This process, known as binary fission, involves the formation of a contractile ring composed of a protein called FtsZ, which helps in the division of the cell into two daughter cells.
Does bacteria have microtubules?
Bacteria do not have microtubules in an eukaryotic sense since they do not have tubulin. However, they do have tubulin homologue FtsZ protein that form structures and perform functions similar to microtubules in eukaryotes. Sometimes these structures are referred to as 'bacteria microtubules'.
Does prokaryotic cells have microfilaments?
Prokaryotic cells do not have microfilaments like eukaryotic cells do. Prokaryotic cells lack many of the membrane-bound organelles found in eukaryotic cells and have a simpler cytoskeleton that typically includes proteins like MreB and FtsZ for cell structure and division.
Are cytoskeletons in prokaryotes?
Yes, some prokaryotes have cytoskeletons, although they are simpler in structure compared to eukaryotic cytoskeletons. Prokaryotic cytoskeletons are involved in maintaining cell shape, cell division, and intracellular transport. Examples of proteins that play a role in prokaryotic cytoskeletons include FtsZ, MreB, and Crescentin.
Do prokaryotic cells have a simple cytoskeleton?
Internal environment of prokaryotes is very simple and does not have any typr of cytoskeleton.The organelles are poorly developed and DNA does not exist insides the nucleus.Prokaryotes possesses a circular DNA surrounded by few poorly developed cytoplasmic organelles.
How does streptococcus pneumonia?
S. pneumoniae reproduces through a mechanism known as binary fission. It involves the cell copying it's genetic material then splitting in two by a ring of proteins called the FTsZ ring.

Are microtubules prokayote or eykaryote?
Microtubules (actin and tubulin) are cytoskeleton of eukaryote (and not prokaryote). Prokaryote do have cytoskeleton system such as FtsZ.

How does staph infection reproduce?
it reproduces when people spread it to one another. by sharing things and by coughing or sneezing and especially for not covering your mouth. it gets on one spot and then starts doubling.
Are cytoskeletons in prokaryotes?
Yes, some prokaryotes have cytoskeletons, although they are simpler in structure compared to eukaryotic cytoskeletons. Prokaryotic cytoskeletons are involved in maintaining cell shape, cell division, and intracellular transport. Examples of proteins that play a role in prokaryotic cytoskeletons include FtsZ, MreB, and Crescentin.
What do other organisms have that prokaryotes don't?
Prokaryotes differ with other organisms in they don't have definite nucleus, nuclear envelop is absent. nucleolus is absent. no mitosis instead they show amitosis mediated by divisomes ( septasome ) which include the protein FtsZ ( filaments that are temperature sensitive Z ).

Do bacteria cells have a cytoskeleton?
Yes, bacterial cells do have a cytoskeleton, although it is simpler compared to eukaryotic cells. It helps maintain cell shape, facilitate cell division, and assist in cell movement. Some examples of bacterial cytoskeletal proteins include FtsZ, MreB, and Crescentin.
What are the two ways that archaea can reproduce?
Archaea reproduce asexually by binary or multiple fission, fragmentation, or budding; meiosis does not occur, so if a species of archaea exists in more than one form, all have the same genetic material. Cell division is controlled in a cell cycle after the cell's chromosome is replicated and the two daughter chromosomes separate, the cell divides. Details have only been investigated in the genus Sulfolobus, but here that cycle has characteristics that are similar to both bacterial and eukaryotic systems. The chromosomes replicate from multiple starting-points using DNA polymerases that resemble the equivalent eukaryotic enzymes. However, the proteins that direct cell division, such as the protein FtsZ, which forms a contracting ring around the cell, and the components of the septum that is constructed across the center of the cell, are similar to their bacterial equivalents.Both bacteria and eukaryotes, but not archaea, make spores. Some species of Haloarchaea undergo phenotypic switching and grow as several different cell types, including thick-walled structures that are resistant to osmotic shock and allow the archaea to survive in water at low salt concentrations, but these are not reproductive structures and may instead help them reach new habitats.
What are the basic steps in asexual reproduction among bacteria?
They reproduce by Process called BINARY FISSION 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. The cell membrane then invaginates (grows inwards) and splits the cell into two daughter cells, separated by a newly grown cell plate.
