WebView history. In biology, phase variation is a method for dealing with rapidly varying environments without requiring random mutation. It involves the variation of protein expression, frequently in an on-off fashion, within different parts of a bacterial population. As such the phenotype can switch at frequencies that are much higher (sometimes ... WebQuestion 3 What is the O antigen of Enterobacteriaceae?

K antigens are components of the polysaccharide capsule or pilus-like proteins, H antigens are located on flagella, and O antigens compose the outer polysaccharide chains linked to the core lipopolysaccharide (LPS) of the bacterial cell wall of gram-negative bacteria. O antigen ... WebNov 9, 2024 · The bacterial flagellar filament is an extracellular tubular protein structure that acts as a propeller for bacterial swimming motility. It is connected to the membrane-anchored rotary bacterial flagellar motor through a short hook. The bacterial flagellar filament consists of approximately 20,000 flagellins and can be several micrometers long. church in oc md
