Transposons Transposable elements, or transposons, are jumping genes; these are DNA fragments that can move within a genome. Transposons are not replicons, they do not replicate autonomously. Transposons are not episomes, transposons only exist in association with a segment of DNA with an origin of replication. The limits of transposons are defined by the inverted repeat DNA process. Inverted repeat sequences exist on both ends of an insertion sequence. The IS element contains only the genes

Unformatted text preview: for the those enzymes required for its transposition and bound is bounded at both ends by inverted repeats. Transposons contain very few genes: the transposase gene required for transposition, and may contain genes encoding for antibiotic resistance or toxins. Transposons can insert into a gene, and it is possible to produce mutation if indiscriminate insertion changes the reading frame. Transposons exist in bacteria, plants, and animals....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
