A single or a few new gene structures can be formed at one time by DNA-based duplication (the copying and pasting of DNA sequence from one genomic region to another) or retroposition. DNA-based duplications are often tandem.

Web13 de abr. de 2024 · Definition. Duplication, as related to genomics, refers to a type of mutation in which one or more copies of a DNA segment (which can be as small as a few bases or as large as a major chromosomal region) is produced. Duplications occur in all organisms. For example, they are especially prominent in plants, although they can also … WebDuplications and deletions often produce offspring that survive but exhibit physical and mental abnormalities. Cri-du-chat (from the French for “cry of the cat”) is a syndrome associated with nervous system abnormalities and identifiable physical features that results from a deletion of most of the small arm of chromosome 5 ( Figure 7.11 ).
