Genetic Engeneering

Question 1

What is genetic engineering?

Answer 1

Genetic engineering is more precise and quick then selective breeding, now this means they can alter the organisms genes to produce an organism with desired characteristics. E.g. Crops that are resistant to disease.

Question 2

Advantage of genetic engineering-

Answer 2

A very precise process as single genes can be targeted and much quicker, it can change in one generation

Question 3

Examples of genetic modification:

Answer 3

• cotton
• corn
• bacteria

Question 4

How do you alter organisms genes?

Answer 4

Takes genes from another organism that shows a desired characteristic, known as foreign genes. Then this gene is placed in a plant or animal at a early stage of its development.

Question 5

Name two useful chemicals produced by genetically engineered bacteria.

Answer 5

Antibiotics and vaccines.

Question 6

Complete-
Scientists can insert- -
genes into organisms to produce desired - -.
This is called - - engineering. For example, bacteria can be engineered to produce - -

Answer 6

Scientists can insert -FOREIGN - genes into organisms to produce desired - CHARACTERISTICS-. this is called -GENETIC- engineering. for example bacteria can be engineered to produce - ANTIBIOTICS-
