In this article we will discuss about the meaning of transposable elements. The chromosomes of E. coli and other prokaryotes contain discrete moveable segments of DNA called transposable elements, which can be translocated to other locations. Such DNA sequences can move from one position on a chromosome to another, and from one DNA molecule to another. They are detected when [...]
In this article we will discuss about:- 1. Meaning of Transposable Elements 2. Nomenclature of Transposable Elements 3. Classes. Meaning of Transposable Elements: For a long time it was assumed that the genes have fixed chromosomal locations. Genetic recombination is a common process of a cell within which exchange between the homologous DNA sequences takes place. Over the past few [...]
The below mentioned article provides a study note on transposable elements. The term "transposon" was coined by Hedges and Jacob in 1974 for mobile discrete DNA sequences in the genome; such sequences are able to transport themselves from one location to the other locations within the genome. These sequences are also called transposable genetic elements. Transposable genetic elements are found [...]
