biotech and genetic modification

Question 1

biotechnology

Answer 1

the exploitation of biological processes by humans for industrial and other purposes
- Example. Lactase used to produce lactose-free milk

Question 2

genetic engineering

Answer 2

involves changing the genetic material of an organism by removing, changing or inserting individual genes

Question 3

Why are bacteria useful in biotechnology?

Answer 3

they reproduce rapidly and can make complex compounds

Question 4

Main steps in genetic modification:

Answer 4

1. Isolating the section of DNA that makes up the required human gene.
2. Cutting the DNA of a bacterial plasmid .
3. Inserting the human DNA into the plasmid DNA.
4. Inserting the plasmid into bacteria.
5. Allowing the genetically modified bacteria to express the gene and make the human protein.
