genetic engineering

Multiple Choice

Some farmers currently grow genetically engineered crops. An argument against the use of this technology is that

• it increases crop production

• it produces insect-resistant plants

• its long-term effects on humans are still being investigated

• it always results in crops that do not taste good

Multiple Choice

White short-horned cattle and Black Angus cattle have been crossed to produce offspring with superior beef and rapid growth qualities. This process of choosing organisms with the most desirable traits for mating is known as

• cloning

• biodiversity

• selective breeding

• genetic engineering

Multiple Choice

Which statement explains how a population’s genetic variability and diversity can be affected by selective breeding?

• Genetic variability and diversity decrease because only select individuals are bred.

• Genetic variability and diversity increase because only select individuals are bred.

• Genetic variability increases and diversity decreases because only select individuals are bred.

• Genetic variability decreases and diversity increases because only select individuals are bred.

Multiple Choice

Selective breeding is where ___________ decides which traits should be passed on

• Nature

• A human

• Mrs. Yezak

• The illuminati

Multiple Choice

Using genetic engineering to treat or cure diseases is called:

• Bacterial transformation

• Selective breeding

• Gene therapy

• Alternative medicine

Multiple Choice

Which of the following correctly identifies the difference between genetic engineering and selective breeding?

• Genetic engineering is an example of artificial selection and selective breeding is an example of natural selection

• With selective breeding you choose the traits you want but the organisms still have to mate, with genetic engineering the actual gene is changed

• With selective breeding the actual gene is changed, with genetic engineering you choose the traits you want but the organisms still have to mate

• Genetic engineering only causes disadvantages and selective breeding only causes advantages

Multiple Choice

Scientists genetically engineer corn to be immune to corn diseases. This is BENEFICIAL because

• This causes corn to be less likely to reproduce
• This causes corn to be less likely to survive
• This causes corn to be smaller
• This allows increased production of corn

Multiple Choice

The purpose of gene therapy is to

• remove mutations from genes

• cure genetic disorders

• determine the sequences of genes

Multiple Choice

A farmer grows beans that he sells to local markets. Over a period of 40 years, the farmer has identified the plants that produced the most beans and only used those beans to produce new plants. This procedure is part of the process of

• selective breeding

• replication

• cloning

• gene splicing

Multiple Choice

• genetic engineering

Multiple Choice

Which one of the following statements is an accurate description of genes?

Multiple Choice

 A person with a genetic disease that codes for a specific protein could be a candidate for which of the following? 

• Cloning
• Gene therapy
• DNA fingerprinting
• Gel electrophoresis

Multiple Choice

Why aren't more scientists using gene modification?

• Because they are poor
• Because they are lazy
• Because of ethics and morality
• Because of how long it takes
