E. coli bacteria undergoing binary fission. The cell wall is dividing resulting in the formation of two cells. Janice Carr/CDC. Most prokaryotes reproduce asexually through a process called binary fission. During binary fission, the single DNA molecule replicates and the original cell is divided into two identical cells. Steps of Binary Fission
5 days ago · Bacteriophage. Anatomy and infection cycle of bacteriophage T4. A bacteriophage ( / bækˈtɪərioʊfeɪdʒ / ), also known informally as a phage ( / ˈfeɪdʒ / ), is a virus that infects and replicates within bacteria and archaea. The term was derived from "bacteria" and the Greek φαγεῖν ( phagein ), meaning "to devour".
5 days ago · bacteria, any of a group of microscopic single-celled organisms that live in enormous numbers in almost every environment on Earth, from deep-sea vents to deep below Earth’s surface to the digestive tracts of humans. Bacteria lack a membrane-bound nucleus and other internal structures and are therefore ranked among the unicellular life-forms ...

4 days ago · A colony of Escherichia coli [111] Unlike in multicellular organisms, increases in cell size ( cell growth) and reproduction by cell division are tightly linked in unicellular organisms. Bacteria grow to a fixed size and then reproduce through binary fission, a form of asexual reproduction. [112]
