Topic 6- Genetic Engineering

Question 0

What is genetic engineering?

Answer 0

-viruses and plasmids are known as vectors when they introduce new genes to cells
-we use vectors to transfer genes to another
The genetically modified organism gains a useful characteristic or makes a valuable product

Question 1

Where can genetic information be transferred?

Answer 1

• from one cell to another
• this can happen naturally
• eg. Viruses insert genes into the dna of a host cell
• bacteria pass genes naturally from one to another in plasmids
• viruses and plasmids are known as vectors when the introduce new genes to cells

Question 2

How is the process of genetic engineering done?

Answer 2

• to identify the required gene in the source chromosome
• the gene is cut out using an enzyme
• the gene is inserted into a bacterial plasmid
