Occurrence of a segment of a chromosome twice in the haploid set.
a mutational event that results in a portion of a chromosome being replicated two or more times within the new chromatid copy.
a copy that corresponds to an original exactly; "he made a duplicate for the files"
the act of copying or making a duplicate (or duplicates) of something; "this kind of duplication is wasteful"
A duplicated portion of genetic material, either a gene, section of DNA, or piece of chromosome.
An extra copy of a chromosome segment without altering the number of chromosomes.
another corresponding to the first in all essentials or exactly,...a copy; a transcript: a replica; a facsimile.[Back to Glossary Index
Producing paper or microfiche copies of records.
A type of mutation that occurs when one or more copies is made from any piece of DNA, a gene, or a chromosome.
A mutation which results in doubling up of part of the genetic material the size of which may vary from a single nucleotide to a chromosome segement.
Copying of one type of disc to another using CD/DVD burners
A part of the chromosome is present in two or more copies. If the duplication is large it may be observed under the microscope as a change in a chromosome; a small duplication may only be observed by examining the DNA structure of the chromosome or a gene.
Part of a chromosome in duplicate, a particular kind of mutation (change) involving the production of one or more copies of any piece of DNA, including a gene or even an entire chromosome. See the entire definition of Duplication
A double copy of part of a chromosome resulting in an extra (abnormal) dose of the duplicated material.
Production of a copy using sequential, serial transfer of information elements from an original image to a duplicate. Low mastering and equipment costs and short preparation times are offset by low throughput, often limiting use to low volumes. Examples would be CD-R duplication from a digital master, or making copies of text using a line printer.
A sometimes, but not always, cytologically visible doubling of a section of the genome. The duplicated segment may be contiguous with the original one (tandem duplication), contained elsewhere in the same chromosome (intrachromosomal duplication), or incorportated in a nonhomologous chromosome (interchromosomal duplication).
The process of producing one or more copies of the microfilm.
The presence of an extra segment of DNA, resulting in redundant copies of a portion of a gene, an entire gene, or a series of genes, usually caused by unequal crossing-over during gene replication when gametes are formed in meiosis
occurs when there are two copies of the same genetic material in a genome, this can be a gene or and entire chromosome.
Doubling of a chromosome section or gene.
A chromosome rearrangement that duplicates a given region of DNA. Duplications may occur in tandem or the sequences may be inverted.
More than one copy of a particular chromosomal segment in a chromosome set.
Where a part of a chromosome or gene is duplicated.
when a part of a chromosome is present in two copies.
Copying or dubbing from one tape to another or from one film format to another.
Inclusion of two copies of the same genetic material in a genome. A chromosome aberration resulting from unequal crossing over or exchange of segments between two homologous chromosomes.
