Duplication
Duplication (medicine)
Duplication (pronounced: doo-pli-KAY-shun) in the field of medicine refers to the occurrence of a repeated segment of the genetic material or structure within an organism's genome. This can occur in a variety of forms, including gene duplication, chromosome duplication, and genome duplication.
Etymology
The term "duplication" originates from the Latin word "duplicare", which means "to double". In the context of genetics and medicine, it refers to the doubling or repetition of a specific segment of genetic material.
Related Terms
- Gene Duplication: This is a type of mutation that results in two copies of a gene instead of the usual single copy. This can lead to the evolution of new functions for the duplicated gene.
- Chromosome Duplication: This is a type of mutation where a segment of a chromosome is repeated, leading to an increase in the number of genes on that chromosome.
- Genome Duplication: This is a type of mutation where the entire genome of an organism is duplicated. This can lead to the evolution of new species.
- Mutation: This is a change in the DNA sequence of a gene or chromosome. Mutations can lead to changes in the function of genes and can cause diseases.
- Genome: This is the complete set of genetic material in an organism. It includes all of the genes and non-coding DNA sequences.
- Genetics: This is the study of genes, genetic variation, and heredity in living organisms.
