Title: The roles of proteins in bacterial cell division and eukaryotic cytokinesis Post by: Reisolated on Nov 3, 2013 The division of a bacterial cell into two daughter cells (called binary fission) is accomplished by a protein called FtsZ. FtsZ is very similar to the tubulin subunits that form microtubules in eukaryotes. After the replicated bacterial chromosomes have moved to opposite ends of the cell, a ring of FtsZ proteins forms inside the plasma membrane in the region where the cell will divide. As the FtsZ ring constricts, the plasma membrane and bacterial cell wall fold in and eventually separate into two cells.
Plant and animal cells also require cytoskeletal proteins for cytokinesis, although the roles these proteins play differ among bacteria, plants, and animals. For each space in the table, drag the appropriate label to indicate if the statement is true or false for each group of organisms. True Or False Answers 1. Cells divide by constriction of a ring of protein. Bacteria: Animals: Plants: 2. The presence of a cell wall prevents the cell from dividing by constriction. Bacteria: Animals: Plants: 3. Tubulin or tubulin-like molecules function in binary fission (in bacteria) or cytokinesis (in animals and plants). Bacteria: Animals: Plants: Can someone help me out with this question? Thanks.

Looking forward to your reply.

Title: Re: The roles of proteins in bacterial cell division and eukaryotic cytokinesis Post by: padre on Nov 3, 2013 1. Cells divide by constriction of a ring of protein is True for Bacteria. The cell division in bacteria is accomplished by a protein called FtsZ. The FtsZ ring constricts the plasma membrane and causing folding in the cell wall, eventually results in formation of two daughter cells.
2. The presence of a cell wall prevents the cell from dividing by constriction is False for Bacteria. Plants may contain cell wall but it is rigid in nature. So, the contriction of a ring of proteins cannot fold the cell wall but produce a cell wall between the daughter cells by the formation of a cell plate, joining the existing cell wall. Thus presence of cell wall doesn't prevent the cell from dividing by constriction in bacteria. 3. Tubulin subunits or tubulin-like molecules function in the division of the cell is True for Bacteria and Plants, false for Animals.
