Lesson 4- Genetic Engineering

Question 1

An organism described as (blank), contains genes from other species.

Answer 1

transgenic

Question 2

Genetic engineering has spurred the growth of (blank).

Answer 2

biotechnology

Question 3

Transgenic Microorganisms

Transgenic bacteria produce important substances useful for health and industry. Transgenic bacteria have been used to produce:

Answer 3

• insulin
• growth hormone
• clotting factor

Question 4

(Blank) (blank) have been used to study genes and to improve the food supply.

Mice have been produced with human genes that make their immune systems act similarly to those of humans. This allows scientists to study the effects of diseases on the human immune system.

Answer 4

Transgenic animals

Question 5

Researchers are trying to produce (blank) (blank) that will be resistant to the bacterial infections that can cause food poisoning.

Answer 5

transgenic chickens

Question 6

(Blank) are now an important part of our food supply.

Many of these plants contain a gene that produces a (blank) (blank), so plants don’t have to be sprayed with pesticides.

Answer 6

Transgenic plants, natural insecticide

Question 7

A (blank) is a member of a population of genetically identical cells produced from a single cell.

Answer 7

clone

Question 8

Researchers hope cloning will enable them to make copies of transgenic animals and help save endangered species.

Studies suggest that cloned animals may suffer from a number of (blank) (blank) and (blank) (blank).

Answer 8

genetic defects and health problems.
