2.29: L.2 Biotechnology

Biotechnology uses a procedure called genetic engineering.

Which best describes genetic engineering?

• making artificial DNA in the laboratory from chemicals

• cutting out pieces of DNA from an organism under a microscope

• adding DNA from one organism into the DNA of another organism

• creating DNA from scratch for an organism

How has genetic modification most likely affected the safety and availability of fruits and vegetables?

• It has decreased the safety and availability of fruits and vegetables. 

• It has increased the safety and availability of fruits and vegetables. 

• It has decreased the safety of food, but increased the availability of fruits and vegetables. 

• It has increased the safety of food, but decreased the availability of fruits and vegetables.

Bacteria cells can be used to produce insulin for the treatment of diabetes in humans. Which best explains how the bacteria cells are able to produce insulin for humans?

• The bacteria have been grown on a petri dish containing insulin.

• The bacteria have been genetically engineered to contain the DNA needed to produce insulin.

• The bacteria have been exposed to radioactivity to create mutant strains capable of producing insulin.

• The bacteria have been grown on a petri dish containing sugar; the bacteria produce insulin in response to the sugar

North Carolina has over 400 biotechnology companies. How would the economy most likely change if that number were reduced by half?

• The economy would decline because of job loss.

• The economy would suffer as funding for research decreases.

• The economy would increase due to an increase in production.

• The economy would improve when the government offers assistance.

How has genetic engineering helped farming?

• by developing better fertilizer for crops

• by creating crops that resist some diseases

• by producing soil that makes crops grow better

• by producing faster ways to harvest crops

How can biotechnology help farmers overcome sudden changes in the global climate?

• by changing the types of soil in which the crops are planted

• by developing crops that are resistant to adverse weather

• by rotating the crops within the same field

• by only planting crops in the winter

What is involved in creating genetically modified bacteria?

• allowing them to reproduce freely

• changing their food source

• using biotechnology techniques

• growing them on selected plants

Which is a way the agricultural biotechnology industry could have a positive impact on the environment?

• by producing crops that are virus resistant

• by making robots to replace large farm machines

• by reducing the need for countries to import food

• by increasing the use of wind farms that produce electricity
