STS: GMO Flashcards
(45 cards)
Considered as the basic unit of inheritance
Gene
Segment of DNA strand that may or may not code for specific proteins, which have different
functions within the Chromosome body
gene
ALL of the genetic materials contained in the chromosome of an organism
genome
Artificial manipulation and alteration of
a species’ genetic material ni a laboratory
Usually associated with recombinant DNA technology
artificial engineering
Recombinant DNA technology
- involves the group of techniques used to cut up and join together genetic material, esp. DNA from
different biological species, and to introduce the resulting hybrid DNA into an organism to form new combinations of heritable genetic material.
GENETIC ENGINEERING
Produces genetically modified organisms (GMOs)
GENETIC ENGINEERING
Plant, animal, bacteria, and virus genes may be combined or crossbred to produce another kind of species that do not naturally Occur in the environment
GENETICALLY MODIFIED ORGANISMS [GMOS)
who discovered DNA
James Watson and Francis Crick
first to genetically modify an organism:
genes of two different E. coli were combined
Herbert Boyer and Stanley Cohen -
Bacterium
Herbert Boyer and
Stanley Cohen
resistant to antibiotic kanamycin.
Bacterium
used in research a models of human disease
Mouse (1974)
Mouse (1974)
Rudolf Jaenisch
resistant to antibiotics
Tobacco (1983)
led a projectin Scotland
Ian Wilmut
Resistant to ring spot virus produced Bacillus Thuringienis
GM Papaya in hawaii
to address vitamin A deficiency in asian countries
golden rice
found in feasting on Bt cotton crops
Bt toxin resistant caterpillar moth Helicoverpazea
to produce offspring producing the salivary
enzyme phytase- digests plant phosphorus
yorkshire pigs
won the case against Monsant of or chemical
poisoning caused by the pesticide Lasso (Roundup
Readyproduct
French farmer Paul Francois
bio fuel production as efficient substitute for petroleum products
GM corn and poplars
Variety of Oryza sativa
Modified to biosynthesize beta-carotene, a precursor of vitamin A
golden rice
Additional three Beta -carotene-synthesized genes
Its introduction was opposed -> thought to compromise food production, nutrition, and financial security
