Unit 1.5 Genetic Engineering

Question 1

What can genetic engineering do

Answer 1

Genetic engineering can transfer genetic information from one cell to another

Question 2

What are the stages of genetic engineering

Answer 2

1. Identify section of DNA that contains required gene from source chromosome
2. Extract required gene
3. Extract plasmid from bacterial cell
4. Insert required gene into bacterial plasmid
5. Insert plasmid into host bacterial cell to produce a genetically modified (GM) organism

Question 3

How are enzymes used in genetic engineering

Answer 3

Enzymes cut open human DNA to extract the required gene, to cut the plasmid open and to seal the human gene into the bacterial plasmid
