29692996plasmidcircular DNA that replicates separately from the bacterial chromosome3
29692997gene cloningmaking multiple copies of a single gene4
29692998restriction enzymesthey snip sugar phosphate backbones to create "sticky ends"5
29692999restriction sitethe specific cutting site of a plasmid6
29693001restriction fragmenta DNA segment that results from the cutting of a restriction enzyme7
29693002sticky endthe end off of a restriction fragment8
29693003DNA ligaseglues restriction fragments together9
29693006cloning vectorA gene carrier/plasmid that transfers DNA from a foreign cell or test tube to another cell10
29693007genomic librarya complete set of plasmid-carrying cell clones, each carrying copies of a particular segment from the initial genome11
29693009bacterial artificial chromosome (BAC)another type of vector; allows for easier replication/manipulation as the number of genes is reduced to a smaller size12
29693010complementary DNA (cDNA)a complementary, single-stranded, DNA molecule to another mRNA or DNA; composed by mRNA via reverse transcriptase13
29693011cDNA librarya collection of cDNAs14
29693016nucleic acid hybridizationthe process of detecting a certain gene by adding a radioactive probe composed of complementary nucleotides15
29693017nucleic acid probean artificially synthesized nucleotide complement used in nucleic acid hybridization16
29693018expression vectorallows a cloned eukaryotic gene to function in a bacterial host; a cloning vector that contains a highly active bacterial promoter upstream of a restriction site where the eukaryotic gene can be inserted into the correct reading frame17
29693019yeast artificial chromosome (YAC)essentials of a eukaryotic chromosome (DNA origin of replication, centromere, and 2 telomeres) inserted with foreign DNA to help a eukaryotic gene function18
29693021electroporationthe act of sending an electric pulse to a cell in membrane saturated solution to allow DNA to enter19
29693022polymerase chain reaction (PCR)the act of amplifying a target DNA sequence; consists of denaturation, cooling with primers, and the DNA pol adding of nucleotides20
29693024gel electrophoresisthe process of separating nucleic acids/proteins based on size, electrical charge, and other physical properties21
29693026southern blottinga process involving both gel electrophoresis and nucleic acid hybridization to detect a specific nucleotide sequence of a specific gene on DNA22
29693027northern blottinga process involving both gel electrophoresis and nucleic acid hybridization to detect a specific nucleotide sequence of a specific gene on mRNA23
29693032reverse transcriptase-polymerase chain reaction (RT-PCR)a process using cDNA, PCR, and gel electrophoresis to compare gene expression between samples24
29693033in situ hybridizationusage of placing probes in an organism with fluorescent dyes to determine which tissues/cells are expressing certain genes25
29693034DNA microarray assaya collection of many small, single-stranded DNA fragments in a glass slide that would ideally represent all genes of an organism26
29693035in vitro mutagenesisthe process of determining the function of a gene by disabling it via mutation27
29693036RNA interference (RNAi)a synthetic, double-stranded RNA acting as a sequence of a particular gene to block translation of a specific protein28
29693037totipotentdescribes a cell that can dedifferentiate29

29693041single nucleotide polymorphism (SNP)where a single base pair site is varied33
29693043restriction fragment length polymorphism (RFLP)an SNP that exists on the restriction site for a particular enzyme making it unrecognizable causing different restriction fragments to show during gel electrophoresis34
29693048gene therapyintroducing genes into an afflicted individual for therapeutic purposes35
29693050transgenican organism that has genes from another organism of the same or different species36
29693051genetic profilean individual's set of unique genetic markers37
