selective breeding and genetic engineering

Question 1

genetic engineering

Answer 1

changing the dna of one organism, often by inserting the genes of different organisms. There are advatages and disadvantages to this

Question 2

advantages of GMOs

Answer 2

fruits and vegetables can be genetically modified to give other vitamins and become disease resistant

pigs are genetically modified to have human-like organs for organ transplants

Question 3

in selective breeding, all organisms would be similar so if a change in conditions affected one organism, all others would be affected

it is very expensive

Question 4

plasmid

Answer 4

small circles of dna

Question 5

ligase

Answer 5

enzyme used for combining sticky ends together

Question 6

restriction enzyme

Answer 6

used to cut a piece of bacteria

Question 7

sticky ends

Answer 7

strands of DNA with unpaired bases at the end

Question 8

vector

Answer 8

a dna molecule used to carry new dna into another cell
