Category:Mobile Genetic Elements
Mobile genetic elements are a type of genetic information that can move around within genome(s) or cells.
In E. coli, they include:
What's the difference between an insertion sequence and a transposon?
Insertion sequences are mobile genetic elements that contain genes only directly related to insertion functions. Transposons contain additional genes unrelated to insertion functions, such as antibiotic resistance genes. 
Naming Conventions In E. coli
- The convention for indicating the presence of an IS element or transposon is the gene name interrupted followed by a double colon and the IS or Tn. For example, lacZ98::Tn10 or lacZ::IS1.
