Chimeric gene

Chimeric Gene

A Chimeric Gene (pronounced: /kaɪˈmɛrɪk/ gene) is a gene that is derived from two or more previously independent genes. The term is derived from the mythical creature Chimera in Greek mythology, which was a hybrid creature composed of parts of different animals.

Etymology

The term "Chimeric" is derived from the Greek word "Chimaira", which refers to a mythical beast that was a hybrid of a lion, goat, and serpent. In the context of genetics, a chimeric gene is a hybrid gene that is formed from the fusion of two previously separate genes.

Formation

Chimeric genes can form in several ways, including gene duplication, genetic recombination, and translocation. These processes can lead to the creation of a new gene that has properties of both parent genes.

Function

The function of a chimeric gene depends on the properties of the parent genes from which it was formed. Some chimeric genes can have beneficial effects, such as providing a new function that helps an organism adapt to its environment. However, other chimeric genes can have harmful effects, such as causing cancer or other diseases.

Related Terms

Fusion Gene: A gene that is formed by the fusion of two separate genes. This is similar to a chimeric gene, but the term "fusion gene" is often used when the fusion occurs as a result of a genetic mutation or abnormality.
Hybrid Gene: Another term for a chimeric gene. This term is often used in the context of plant genetics, where hybrid genes can be created through cross-breeding.
