5781405953CloningThe production of genetically identical copies of DNA, cells, or organisms through some asexual means.0
5781405954Transgenic OrganismsAn organisms whose genome has been altered by the insertion of genes from another species.1
5781405955rDNARecombinant DNA - DNA that contains genes from more than one source.2
5781405956VectorIn genetic engineering, a means to transfer foreign material into a cell. (ex. a plasmid)3
5781405957PlasmidsExtrachromosomal ring of accessory DNA in the cytoplasm of prokaryotes.4
5781405958Restriction EnzymeBacterial enzyme that stops viral reproduction by cleaving viral DNA; used to cut DNA at specific points during production of recombinant DNA.5
5781405959DNA LigaseEnzyme that links DNA fragments.6
5781405960PCRPolymerase Chain Reaction - Technique that uses the enzyme DNA polymerase to produce millions of copies of a particular piece of DNA.7
5781405961STRsShort tandem repeat sequences - Procedure of analyzing DNA in which PCR and gel electrophoresis are used to create a banding pattern; these are usually unique for each individual.8
5781405962Genetically modified organismsOrganism whose genetic material has been altered or enhanced using DNA technology.9
5781405963Gene pharmingProduction of pharmaceuticals using transgenic organisms, usually agricultural animals.10
5781405964Ex vivo gene therapyGene therapy in which cells are removed from an organism, and DNA is injected to correct a genetic defect. The cells are returned to the organism to treat a disease or disorder.11
5781405965In vivo gene therapyGene therapy in which a gene is delivered directly into the body.12
5781405966GenomicsArea of study that examines the genome of a species or group of species.13
5781405967Human Genome ProjectInitiative to determine the complete sequence of the human genome and to analyze this information.14
5781405968Tandem RepeatRepetitive DNA sequence in which the repeats occur one after another in the same region of a chromosome.15
5781405969TransposonsDNA sequence capable of randomly moving from one site to another in the genome.16
5781405970DNA microarraysGlass or plastic slide containing thousands of single-stranded DNA fragments aranged in an array (grid); used to detect and measure gene expression.17
5781405971ProteomicsStudy of the complete collection of proteins that a cell or organism expresses.18
5781405972BioinformaticsArea of scientific study that utilizes computer technologies to analyze large sets of data, typically in the study of genomics and proteomics.19
5781405974biotechnology productsCommercial or agricultural products that are made with or derived from transgenic organisms.20
5781405977functional genomicsArea of genomics that studies the functions or roles of genetic information contained within genomes.21
5781405978gene cloningproduction of multiple copies of a single gene22
5781405979gene therapyThe insertion of working copies of a gene into the cells of a person with a genetic disorder in an attempt to correct the disorder23
5781405981intergenic sequenceRegion of DNA that lies between genes on a chromosome.24
5781405983repepititve DNA elementa sequence of two or more nucleotides that are repeated many times on a length ofDNA25
5781405984structural genomicsArea of genomics that studies the organization and sequence of information contained within genomes; sometimes used by protein chemists to refer to the determination of the three-dimensional structure of proteins26
5781405985xenotransplantationThe transplantation of living cells, tissues or organs from one species to another, such as from pigs to humans.27
