KA5: Genetic Engineering

Question 1

What is genetic engineering?

Answer 1

The transfer of DNA from one organism to another using biotechnology

Question 2

In genetic engineering, what is removed from the chromosomes

Answer 2

The gene

Question 3

In genetic engineering, what us removed from the bacterial cell

Answer 3

A plasmid

Question 4

What are the stages of genetic engineering

Answer 4

1. Extract DNA from some human cells
2. Use an enzyme to cut the gene out of the DNA
3. Use the same enzyme to cut bacteria DNA plasmid
4. Use a different enzyme to stick the human gene into the plasmid
5. The modified plasmid is put into a host bacterium
6. The GM bacteria cells multiply

Question 5

What makes bacteria ideal hosts for genetic engineering?

Answer 5

They reproduce very quickly
