Biotechnology
Term | Definition |
---|---|
environment | "The conditions and circum- stances surrounding an organism." |
Plant Breeding | "The selection and collection of seeds from desirable plants to encourage their traits in future plant production." |
Enzyme | " A large, complex protein molecule produced by the body that stimulates or speeds up various chemical reactions without being used up itself; an organic catalyst." |
Rennin | " A coagulant enzyme occurring particu- larly in the gastric juice of calves and also in some plants and lower animals." |
Fermentation | "The processing of food by means of yeasts, molds, or bacteria." |
Yeast | " A yellowish substance composed of mi- croscopic, unicellular fungi of the family Saccha- romycetaceae that induces fermentation in juices, worts, doughs, and so forth." |
Hereditary | "The traits that are passed to an off- spring from the parents." |
law of segregation | " A law, developed by Gregor Mendel in the nineteenth century, that says that the factors responsible for the traits from each par- ent are separated and then combined with factors from the other parent at fertilization". |
Law of independent assortment | "A law which states that factors (genes) for certain characteris- tics are passed from parent to the next genera- tion and are separate from the other factors or genes that transmit other traits; this separation allows the tremendous amount of diversity a |
cell | "The ultimate functional unit of an organic structure, plant, or animal. It consists of a micro- scopic mass of protoplasm that includes a nucleus surrounded by a membrane. In most plants, it is surrounded by a cell wall." |
vaccine | " A substance that contains live, modi- fied, or dead organisms or their products that is injected into an animal in an attempt to protect the host from a disease caused by that particular organism. |
antibiotic | "Germ-killing substances produced by a bacterium or mold." |
artificial insimination | The deposition of sper- matozoa in the female genitalia by artificial rather than natural means. |
embryo transfer | " The process of removing an embryo from a superior female and implanting it into an inferior female." |
genetic code | " A process of removing a desirable gene from one organism and transplant- ing it into another organism." |
vertical gene transfer | " The transfer of genetic information from parents to offspring." |
DNA | "A genetic pro- teinlike nucleic acid on plant and animal genes and chromosomes that controls inheritance." |
Double Helix | "Description of the two spiral- shaped strands of phosphoric acid and deoxyribose found within the nucleus of cells." |
Genetic engineering | Manipulating the genes of organisms. |
Horizontal Gene Transfer | "A process in which microbes are natural “genetic engineers” transfer- ring genetic material between cells." |
Gene Splicing | "The process of removing and/or inserting genetic material in order to change an organism’s traits." |
