Exon shuffling mechanism
WebExon shuffling is an essential molecular mechanism for the formation of new genes. Many cases of exon shuffling have been reported in vertebrate genes. These discoveries revealed the importance of exon shuffling in the origin of new genes. However, only a few cases of exon shuffling were reported from plants and invertebrates, which gave rise to … WebExon shuffling is a molecular mechanism for the formation of new genes. It is a process through which two or more exons from different genes can be brought together …

It occurs by recombination, aneuploidy, transposition, polyploidy, and error in DNA replication. 2.Transposable Components This refers to a DNA region that can be inserted anywhere in the genome. Ty elements in Drosophila, for example.
WebFeb 8, 2016 · The exon shuffling between completely different genes would not occur by crossing over; there are other mechanisms that would lead to these kinds of structural rearrangements in gametes. 2) Would a new allele be formed by a cross-over between exons, and is this a type of mutation? WebExon shuffling is a molecular mechanism for the formation of new genes. It is a process through which two or more exons from different genes can be brought together ectopically, or the same exon can be duplicated, to create a new exon-intron structure. There are different mechanisms through which exon shuffling occurs: transposon mediated exon …
