Comparative genomic hybridization
METHOD TO EVALUATE BIOLOGICAL SAMPLES
Comparative genomic hybridization (CGH); Array-comparative genomic hybridization; ACGH; Array CGH; Comparative Genomic Hybridization; Comparative Genomic Hybridisation; Comparative hybridization; Array comparative genomic hybridisation; Cot 1 DNA; Cot-1 DNA; Comparative genome hybridization; Chromosomal microarray analysis; CGH array; Array comparative genomic hybridization; Array-comparative Genomic Hybridization; Microarray-based comparative genomic hybridization; A-CGH; Array hybridization
Comparative genomic hybridization (CGH) is a molecular cytogenetic method for analysing copy number variations (CNVs) relative to ploidy level in the DNA of a test sample compared to a reference sample, without the need for culturing cells. The aim of this technique is to quickly and efficiently compare two genomic DNA samples arising from two sources, which are most often closely related, because it is suspected that they contain differences in terms of either gains or losses of either whole chromosomes or subchromosomal regions (a portion of a whole chromosome).
Genomic island
PART OF A GENOME THAT HAS EVIDENCE OF HORIZONTAL ORIGINS
Genomic islands; Genetic island
A genomic island (GI) is part of a genome that has evidence of horizontal origins. The term is usually used in microbiology, especially with regard to bacteria.
DNA glycosylase
ENZYMES INVOLVED IN BASE EXCISION REPAIR
GO system; Dna glycosylases; Dna glycosylase; DNA glycosylases; Dna Glycosylase
DNA glycosylases are a family of enzymes involved in base excision repair, classified under EC number EC 3.2.
DNA bank
STORAGE OF PHYSICAL DNA SAMPLES
Dna bank; DNA Bank
DNA banking is the secure, long term storage of an individual’s genetic material. DNA is most commonly extracted from blood, but can also be obtained from saliva and other tissues.
DNA supercoil
COMPRESSED DNA LOOP SUPERCOILED BY PROKARYOTES TO FIT WITHIN A SMALL SPACE
Supercoil; Supercoiling; Dna, circular; Supercoiling of DNA; Positive supercoiling; Twist (DNA); Writhe (DNA); Supercoiled; Superhelical DNA energetics; Surface wrapping of DNA; DNA supercoiling; Circular genome; Supercoiled DNA; Superhelical DNA; Supertwisted DNA; Plectonemic supercoil; Linking number of DNA; Negative supercoiling; Superhelical dna
DNA supercoiling refers to the amount of twist in a particular DNA strand, which determines the amount of strain on it. A given strand may be "positively supercoiled" or "negatively supercoiled" (more or less tightly wound).

DNA sequencing is the process of determining the nucleic acid sequence – the order of nucleotides in DNA. It includes any method or technology that is used to determine the order of the four bases: adenine, guanine, cytosine, and thymine.
Ancient DNA
DNA ISOLATED FROM ANCIENT SPECIMENS
Fossil DNA; Paleo DNA; Ancient DNA analysis; Ancient DNA revolution; Ancient genomes; Paleogenome; Palaeogenome
Ancient DNA (aDNA) is DNA isolated from ancient specimens. Due to degradation processes (including cross-linking, deamination and fragmentation) ancient DNA is more degraded in comparison with contemporary genetic material.
DNA database
DATABASE OF DNA PROFILES
National DNA database; National DNA Database; DNA databank; Dna databanking; DNA Database; Genetic Database; National dna database; Dna database; DNA databases; Forensic DNA database; Genetic genealogy database; Medical DNA database; DNA Index System; Genetic database
A DNA database or DNA databank is a database of DNA profiles which can be used in the analysis of genetic diseases, genetic fingerprinting for criminology, or genetic genealogy. DNA databases may be public or private, the largest ones being national DNA databases.

DNA profiling (also called DNA fingerprinting) is the process of determining an individual's DNA characteristics. DNA analysis intended to identify a species, rather than an individual, is called DNA barcoding.

Genomic DNA
Genomic deoxyribonucleic acid (abbreviated as gDNA) is chromosomal DNA, in contrast to extra-chromosomal DNAs like plasmids. Most organisms have the same genomic DNA in every cell; however, only certain genes are active in each cell to allow for cell function and differentiation within the body.
The genome of an organism (encoded by the genomic DNA) is the (biological) information of heredity which is passed from one generation of organism to the next. That genome is transcribed to produce various RNAs, which are necessary for the function of the organism. Precursor mRNA (pre-mRNA) is transcribed by RNA polymerase II in the nucleus. pre-mRNA is then processed by splicing to remove introns, leaving the exons in the mature messenger RNA (mRNA). Additional processing includes the addition of a 5' cap and a poly(A) tail to the pre-mRNA. The mature mRNA may then be transported to the cytosol and translated by the ribosome into a protein. Other types of RNA include ribosomal RNA (rRNA) and transfer RNA (tRNA). These types are transcribed by RNA polymerase I and RNA polymerase III, respectively, and are essential for protein synthesis. However 5s rRNA is the only rRNA which is transcribed by RNA Polymerase III.
