Define binary fission vs cell division12/26/2023 ![]() ![]() The ring proteins get associated with FtsZ binding proteins and some additional proteins forming a divisome. The FtsZ monomer proteins polymerize and assemble to form a Z ring. ![]() The FtsZ proteins are synthesized and kept available in the early stage of cell division and retains till cytokinesis. FtsZ proteins direct the cytokinesis process. The division of cytoplasm is called as cytokinesis. The division ensures that both daughter cells receive a copy of genome and some cytoplasmic material. Once the replicated chromosome reached at the opposite ends of the elongated cell, the cell starts dividing by forming a septum. The replicated closed circular chromosomes get separated and start travelling towards the opposite poles of the bacterial cell. It is due to the increase in cytoplasmic content and expansion of cell membrane and cell wall. ![]() The DNA replication is followed by increase in bacterial size. The DNA replication is a semi-conservative type where both the daughters cell receives one parental and one new polynucleotide strand. The DNA replication is initiated at the specific point called as origin. In order to replicate the DNA need to be uncoil. In bacteria, the DNA is in the form of nucleoid in the cytoplasm. The produced energy is used for carrying out biological important molecular pathways like protein synthesis and DNA replication. Under sufficient nutrient and optimum physical condition, bacteria are metabolically active and produce energy. Research has found out FTsZ proteins plays a major role in assembling the cell division apparatus. The Binary fission is intensively studied in E.coli. These events are initiated and regulated by series of proteins. In Binary fission type of reproduction, if environment is a favorable, bacterium grows in size, replicate its DNA and segregate the chromosome and lead to cytokinesis forming two daughter cells. The binary fission is simple and quicker than eukaryotic division and hence the bacterial population increases rapidly. It leads to form clones of the parental cell. Due to which bacteria need less time for its DNA replication.īacteria reproduce by binary fission, where a bacterium divides itself into two daughter cells. Compared to eukaryotes, bacterial DNA is smaller and less complex. The bacterial chromosome is present in cytoplasm in the form of nucleoid. Before dividing, bacteria need to replicate its genetic material in order to transfer the vital life process information to its next generation. Bacteria are prokaryotic unicellular organism. ![]()
