M5: Genetically Modified Organisms Flashcards
Who first isolated DNA in 1869.
Friedrich Miescher
Who discovered DNA’s structure in 1953.
Francis Crick and James Watson
Who combined genes from two different viruses for the first time in history in 1972.
Paul Berg
Made the first GM bacteria in 1973.
Herbert Boyer and Stanley Cohen
Made the first GM animal, a mouse, in 1974.
Rudolf Jaenisch
Founded Genentech, the first genetic
engineering company, in 1976.
Herbert Boyer and Robert Swanson
Made the first GM plant, an antibiotic-resistant strain of tobacco, in
1983.
Michael W. Bevan
Richard B. Flavell
Mary-Dell Chilton
First GMO animal; a Zebra fish modified to glow in the dark.
GloFish
A process involving the alteration of the genetic
make-up of one’s organism.
Recombinant DNA technology
The term used to refer to an organism created through recombinant DNA technology; any organism, in which its genetic material (DNA) has been manipulated to produce phenotypic traits, such traits would not occur naturally (by mating or natural recombination).
Genetically modified organism (GMO)
3 main methods of genetic engineering.
Plasmid Method
Vector Method
Biolistic Method
Utilizes small circular pieces of DNA of bacteria with the aid of restriction enzymes; most commonly used method of
modifying the genetic material of any organism.
Plasmid Method
Uses a virus that serves as a vector (carrier) of the desired trait; involves the introduction of the desired trait into the virus, the virus is then inserted into the host cell and will soon replicate
expressing all the desired features.
Vector Method
Also known as the gene gun method; is done by firing a gene gun containing the desired genes into the host; similar to that of vaccination; mainly for the engineering of the plants.
Biolistic Method
GMOs in food and agricultural industries.
Pest resistance
Virus resistance
Herbicide tolerance
Fortification
Cosmetic prevention
These plants are genetically modified to resist certain pests.
