Genetic Engineering

Question 1

What is genetic engineering ?

Answer 1

A process which involves modifying the genome of an organism by introducing a gene from another organism to give a desired effect

Question 2

Give a reason of why genetically engineering plants Is useful

Answer 2

• resistance to diseases

- bigger fruit

Question 3

Where have we genetically engineered bacteria?

Answer 3

To produce insulin in treating diabetes

Question 4

How does genetic engineering work?

Answer 4

Desired genes are cut out

And transferred to the cells of other organisms

Question 5

What are the pros of genetic engineering crops?

Answer 5

• increase yield
• make the nutrients for people in undeveloped countries
• already grown with no problems

Question 6

What are the cons of genetically modifying plants?

Answer 6

• may affect other plant species already alive, this affect the population of insects, reducing farm,and biodiversity
• not fully understood for the affects of human health
• transplanted genes may get out into the natural environment

Question 7

What are the stages of genetic engineering ?

Answer 7

1. Enzymes isolate required gene
2. Gene is inserted into a vector
3. vector is used to insert the gene into the required cells
4. genes are transferred into the organisms cells st an early stage so they develop with the desired characteristics
