Definitions from the WebHomeobox GeneDefinition: A homeobox gene is a type of master regulatory gene that codes for transcription factors, which help determine the body plan and the development of various organs and tissues in a wide range of organisms. Sense 1: In genetics, a homeobox gene refers specifically to a DNA sequence that contains a homeobox motif, a highly conserved sequence of about 180 base pairs that is responsible for encoding the homeodomain. Usage: Homeobox genes play a crucial role in embryonic development by regulating the expression of other genes involved in cell differentiation, pattern formation, and morphogenesis. Example sentence 1 (genetics sense): The mutation in the homeobox gene disrupted the normal development of the organ system, leading to severe defects in the embryo. Sense 2: In a more general context, a homeobox gene can refer to any gene involved in the development or maintenance of an organism's homing behavior, often observed in migratory animals. Usage: Several homeobox genes have been identified in birds, which are thought to play a key role in their remarkable ability to navigate and return accurately to their breeding grounds. Example sentence 2 (homing behavior sense): The studies on Pacific salmon revealed the presence of specific homeobox genes associated with their incredible ability to return to their natal streams for spawning.
