Answer 3

In the production of protein used to diseases 
Insulin (diabetes) 
EPO- erythropoietin
Human growth hormone (steroids)
Bovine growth hormone (cows)

Question 4

How is recombinant DNA used in agriculture?

Answer 4

•transgenic crops with new characteristics

• resistance to herbicides
• resistance to disease
• enhances nutritional value

Question 5

How are transgenic animals used for research?

Answer 5

They serve has models for research

• scientist induce human diseases in mice bc
• They mimic human symptoms
• study disease progress
• test for cute

Question 6

How are transgenic mice created?

Answer 6

Gene extraction is injected to the uterus of surrogate mother. The offspring then become transgenic mice

Question 7

Biotechnology

Answer 7

recombinant DNA technology to produce goods and services

Question 8

Recombinant DNA

Answer 8

joining DNA segments from different sources

Question 9

Restriction Enzymes

Answer 9

A protein that that, when mixed with DNA, cuts the DNA in a specific place.
