BIO... Flashcards
directly manipulate the genes of organisms in the laboratory so they will manifest a wide array of traits
genetic engineering
The resulting organisms are then called….
genetically modified organisms or GMOs
and gene manipulation is accomplished through
recombinant DNA (rDNA) technology
have devoted their resources to establish a genetic engineering and biotechnology laboratory.
Macedonian Academy of Sciences and Arts
- The birth of genetic engineering took place in…when … of Stanford University and … University of California School of Medicine produced the first transgenic organism.
- gave birth to recombinant DNA technology
1972, Stanley Cohen and Herbert Boyer
An organism is said to be … if it has foreign genes incorporated in its genome.
transgenic
are circular DNA molecules in the cytoplasm of bacterial cells that can self-replicate.
Plasmids
first transgenic organism
Escherichia coli
The recombinant DNA was initially called
chimera
mythological creature—Chimera, one that has the head of a …, body of a …, and tail of a …
lion, goat, snake
first transgenic animal was a
mouse
introduced a foreign gene in a mouse embryo
Rudolf Jaenisch in 1974
became the first human protein that can be produced in genetically engineered E. coli.
1976, somatostatin
two years later, … can already be produced by the same bacterial species
insulin
became the first genetically engineered crop, making it resistant to herbicide.
1983, tobacco by Michael Bevan, Richard Flavell, and Mary-Dell Chilton
serves as the blueprint of life
DNA
- specific instructions in cells are present in the form of DNA
fragments called - the most valuable resource in genetic engineering
genes
serve as phenotypic determiners
protein
The first step in the genetic engineering of organisms is to first identify a
gene of interest
This gene of interest is introduced into the cell of a
host organism
a GM crop that received its foreign genes from the soil bacterium Bacillus thuringiensis
Bt corn
an alternative name for the Bt toxin
cry protein
a Japanese biologist, and he determined its capacity to kill silkworms.
