| Term | Definition |
|---|---|
| enviroment | the conditions that surround someone or something |
| plant breeder | " A process in which microbes are natural “genetic engineers” transfer- ring genetic material between cells." |
| enzyme | a chemical substance in animals and plants that helps to cause natural processes (such as digestion) |
| rennin | an enzyme that coagulates milk and is used in making cheese |
| fermentation | chemical breaking down of a substance (as in the souring of milk or the formation of alcohol from sugar) produced by an enzyme and often accompanied by the formation of a gas |
| yeast | a one-celled fungus that produces alcohol during the process of fermentation |
| heredity | the passing on of genes and genetic traits from parent to offspring |
| law of segregation | a principle in genetics: paired inherited units that control the expression of a character (as height or seed color) separate during germ cell formation so that each sperm or egg receives only one member of each pair |
| law of independent assortment | the members of two or more different pairs of inherited units are passed on to a germ cell independently of each other and the various sperms and eggs unite according to the laws of chance sometimes resulting in new combinations of inherited units and of |
| cells | one of the tiny units that are the basic building blocks of living things |
| vaccine | a preparation of killed, weakened, or fully infectious microbes that is given (as by injection) to produce or increase immunity to a particular disease |
| antibiotic | medicine used to kill off infections caused by other bacteria |
| artificial insemenation | "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 | "The order in which four chemi- cal constituents are arranged in huge molecules of DNA;" |
| vertical gene transfer | " The transfer of genetic information from parents to offspring." |
| DNA | " The transfer of genetic information from parents to offspring." |
| double helix | " Description of the two spiral- shaped strands of phosphoric acid and deoxyribose found within the nucleus of cells. |
| genetic egineering | "The process of removing and/or inserting genetic material in order to change an organism’s trait |
| horizontal genetic 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 trait |
