Study Notes
Transposition
- Cut-and-paste transposition describes the process where a transposable element is excised from one site and inserted into another site in the genome.
- Composite transposons are characterized by their movement within and between the bacterial chromosome and various types of plasmids.
- Retrotransposons involve the creation of an RNA copy of the transposable element, which is then reverse-transcribed into a DNA copy and integrated into the genome. This process utilizes an enzyme called reverse transcriptase.
- Transposase is an enzyme that recognizes short inverted repeat sequences flanking transposable elements. These sequences are essential for the excision of the transposable element and its insertion into a new location.
- Retrotransposons transpose via RNA intermediates and are found in all eukaryotes, playing a significant role in genome evolution and regulation.
