genetic engineering

What is genetic engineering?

Genetic engineering involves making changes to the DNA of a living cell or organism

Genetic information can be transferred…

From one cell to another by genetic engineering

What are the stages of genetic engineering?

• identify section of DNA that contains required gene from source chromosome

• Extract required gene

• Extract plasmid from bacterial cell

• Insert required gene into bacterial plasmid

• Insert plasmid into host bacterial cell to produce a genetically modified (GM) organism

• Grow modified cells and extract required product

What do genetic engineering processes need?

The use of enzymes in the process of genetic engineering

Food, medicine and agriculture examples of genetic engineering

• production of insulin - less likely for diseases and death

• Golden rice- to compact vitamin A deficiency, in developing nations.

• Tomatoes with longer shelf life- reduce spoilage during transport, decrease food waste , and maintain firmness
