Definition Of Gene Duplication In Biology

Genetic information and protein synthesis.

Definition of gene duplication in biology. Gene duplication has resulted in gene families which are groups of related genes within an organism s genome. Biology the state or act of dividing as a natural process of growth or a spontaneous action. Is important because it is a way to get new. A particular kind of mutation involving the production of one or more copies of any piece of dna including sometimes a gene or even an entire chromosome.

Definition noun duplication of an entire or a portion of a chromosome. Part of a chromosome in duplicate. Gene duplication happens when an extra copy of a gene is made in an organism s genome. Genes are expressed through the process of protein synthesis.

Supplement chromosomal duplication may lead to mutation and to disorders such as pelizaeus merzbacher disease pmd a rare central nervous system disorder commonly caused by a complete duplication of the region of the x chromosome containing the plp1 gene. Supplement duplication results from an unequal crossing over between misaligned homologous chromosomes during meiosis. Biology articles tutorials dictionary online. The act or process of duplicating or repeating a region in the genetic material or chromosome as in gene duplication and chromosomal duplication.

Gene duplication increases the number of genes in the genome providing opportunities for further evolutionary change. A duplication is the opposite of a deletion. Definition noun general the act or process of duplicating. In some cases the duplication leads to the gain of a new function but in other cases protein function is.

The state of being duplicated. Gene duplication or chromosomal duplication or gene amplification is a major mechanism through which new genetic material is generated during molecular evolution it can be defined as any duplication of a region of dna that contains a gene gene duplications can arise as products of several types of errors in dna replication and repair machinery as well as through fortuitous capture by selfish.
