1.5 Genetic Engineering

Question 1

What is genetic engineering?

Answer 1

Transferring genetic information (DNA) from one cell into another.

Question 2

Explain the process of genetic engineering.
Identify
Extract
Extract
Insert
Insert

Answer 2

(1) Identify the section of DNA that has the gene required, on the source chromosome.

(2) Then you need to extract the gene

(3) And to extract the plasmid from the bacterial cell

(4) Then insert the required gene into a bacterial plasmid

(5) Then insert the plasmid into the host cell (bacteria) to produce a GM organism

Question 3

What are enzymes needed for in genetic engineering?
cut
extract
cut
seal

Answer 3

To cut the DNA to extract the gene, cut the plasmid open and seal the gene into the plasmid.
