Does amitosis occur in bacteria?
Solution
Bacteria are a biological cell type. They make up a large group of prokaryotic organisms. Bacteria come in a variety of shapes, ranging from spheres to rods and spirals, and are typically a few micrometers long. Bacteria were among the first life forms on Earth, and they can be found in almost every habitat.
Complete answer:
Amitosis (a- + mitosis), also known as 'karyostenosis,' direct cell division, or binary fission, is a type of cell division. It is cell proliferation that does not take place during mitosis, the eukaryotic cell division mechanism that is usually considered essential. Ciliates have a polyploid macronucleus that divides amitotically. Unlike normal mitosis, which produces a precise division of parental alleles, amitosis produces a random division.
Amitosis does not involve the maximum condensation of chromatin into chromosomes, which are visible in pairs along with the metaphase plate under light microscopy. It does not involve a mitotic spindle pulling these paired structures in opposite directions to form daughter cells. Instead, it affects nuclear proliferation without involving chromosomes, which is concerning to cell biologists.
Even though amitosis is well-known in ciliates, there is still some doubt about its role in mammalian cell proliferation, perhaps because it lacks the reassuring iconography of mitosis.
Mitosis is a process that occurs in somatic cells, which are cells that are not involved in the production of gametes. Every chromosome is duplicated before each mitotic division, resulting in a complete set of chromosomes in the nucleus of each new cell after division.
bacteria can develop amitosis. Binary fission is another name for it. It is a primitive type of cell division in which the nucleus and cytoplasm are divided directly. In daughter cells, this results in a random distribution of genes.
Thus, yes amitosis occurs in bacteria.
Note:
The growing body of evidence on amitosis suggests that such processes are indeed involved in the production of humans' staggering 37 trillion or so cells, perhaps especially during the fetal and embryonic stages of development, when the majority of these cells are produced, perhaps within the complexity of implantation, perhaps when large numbers of cells are being produced.
