genetic engineering Flashcards
defintion of genetic engineering
changing an organism’s DNA to give it new traits
recombinant DNA
DNA that has genes from more than 1 organism
transgenic organism
organism with recombinant DNA
example of transgenic organism
the cow that produces milk of narcotics
pro
desirable traits in agriculture animals (nutrients pesticide repellent…)
con
cost
ethical human stuf
unhealthy agriculture -may be allergic
environment unbalance (bT gene kills bugs that eat plants, birds die that eat bugs..)
how to make transgenic bacteria
plasmids are cut and thena gene can be cut out or replaced with another
ligation process bonds sticky ends
example of transgenic bacteria
insulin producing bacteria
plant genetic engineerins
1-gene inser into plasmid
2-bacteria infect plant and plant adopts gene into its DNA
example of genetically engineered plant
Bt potatoes (natural pesticide)
bacteria gene maanipulation
1-gene inserrt plasmid
or 2- they take on foreign DNA and add it to their own in the wild
animals gene maniplation
1- insert gene into nucleus of egg cell
2- egg cell inplant into female
3- embryo is transgenic
example of animal genetic engineered
oncomouse
-aways develops cancer because a cancercontrollling gene was taken out
gene knockout
turn off a gene puposely and completely
