| 8075015225 | Recombinant DNA | DNA produced by combining DNA from different sources |  | 0 |
| 8075015226 | Biotechnology | A form of technology that uses living organisms, usually genes, to modify products, to make or modify plants and animals, or to develop other microorganisms for specific purposes. |  | 1 |
| 8075015227 | Plasmids | Small rings of DNA found naturally in some bacterial cells in addition to the main bacterial chromosome. Can contain genes for antibiotic resistance, or other "contingency" functions. |  | 2 |
| 8075015228 | Gene Cloning | The production of multiple copies of a gene. |  | 3 |
| 8075015229 | Restriction enzymes | Enzyme that cuts DNA at a specific sequence of nucleotides |  | 4 |
| 8075015230 | Sticky end | A single-stranded end of a double-stranded DNA restriction fragment. |  | 5 |
| 8075015231 | DNA Ligase | A linking enzyme essential for DNA replication; catalyzes the covalent bonding of the 3' end of a new DNA fragment to the 5' end of a growing chain. |  | 6 |
| 8075015232 | Cloning vector | DNA molecules that can carry foreign DNA into a host cell and replicate there. |  | 7 |
| 8075015233 | Complimentary DNA (cDNA) | is made from mRNA by reverse transcriptase |  | 8 |
| 8075015234 | polymerase chain reaction (PCR) | A method of producing thousands of copies of DNA segment using the enzyme DNA polymerase |  | 9 |
| 8075015235 | gel electrophoresis | Procedure used to separate and analyze DNA fragments by placing a mixture of DNA fragments at one end of a porous gel and applying an electrical voltage to the gel |  | 10 |
| 8075015236 | southern blotting | A hybridization technique that enables researchers to determine the presence of certain nucleotide sequences in a sample of DNA. |  | 11 |
| 8075015237 | reverse transcriptase- PCR | An enzyme encoded by some certain viruses (retroviruses) that uses RNA as a template for DNA synthesis. |  | 12 |
| 8075015238 | Genetic profile | An individual's unique set of genetic markers, detected most often today by PCR or, previously, by electrophoresis and nucleic acid probes. |  | 13 |
| 8075016688 | Transposon | A sequence of DNA that can move about the genome. | 14 | |
| 8075035551 | Gene families | Groups of closely related genes | 15 | |
| 8075041540 | Pseudogenes | Result from mutations that cause a loss of function rather than an enhanced or new function. | 16 |
