Newer gene transfer techniques are electro- and chemical poration, microinjection, and bioballistics.

Microinjection

Other methods do not rely on biological vectors like plasmids and viruses. One of these is called microinjection and involves simply injecting genetic material containing the new gene into the recipient cell. Where the cell is large enough, as many plant and animal cells are, the injection can be done with a fine-tipped glass needle. Somehow the injected genes find the host cell genes and incorporate themselves among them.

Electro- and Chemical Poration

Other methods for direct gene transfer involve creating pores or holes in the cell membrane to allow entry of the new genes. This can be done by bathing cells in solutions of special chemicals—so-called chemical poration—or subjecting cells to a weak electric current—so-called electroporation.

Listening

You are going to listen to the interview with an owner of a restaurant in San Francisco. Before you listen, in groups discuss your answers to the following questions. When you have finished, talk together, compare your answers and try to persuade each other to see your point of view.

- In buying fruits and vegetables, which is more important: taste, texture, color, nutritional value, price, or shelf life? Why?

- Have you ever eaten food that was genetically engineered? What did it look like? What did it taste like?

2. Listen to the interview. Find the answers to the following question:

- Is Joyce Goldstein more in favor of or more against genetically engineered food?

3. Read the statements for Part 1. Then listen to Part 1 and decide whether the statements are true or false. Write T or F next to each statement.

Part 1

- Genetically designed tomatoes are now available in the supermarket.

- Genetically engineered sheese can now be purchased.

- World hunger may be halped with genetically engineered food.

- Last week 1000 chefs decided not to serve genetically engineered food.

- Special labeling is required for genetically engineered food.

- Goldstein owns a restaurant in San Francisco.
