Cell Biology - Genetic Engineering

Question 1

genetic engineering

Answer 1

the manipulation of a bacteria’s ability to transfer plasmids to artificially transfer genetic information

Question 2

steps of genetic engineering

Answer 2

1. identify section of DNA that contains required gene from the source chromosome
2. an enzyme is used to extrat the required gene from the source chromosome
3. a plasmid is removed from the bacterial cell and cut open using enzymes
4. a different enzyme is used to insert and seal the gene into the bacterial plasmid
5. the altered plasmid is inserted into a host bacterial cell and given the optimum conditions to multiply. each bacterium produced has been geneically modified.

Question 3

importance of genetic engineering

Answer 3

insulin and human growth hormones are examples of two useful substances to humans that are available due to genetic engineering
