Biotechnology 1.2 HW

What is biotechnology?

• The study of plants and animals

• The use of living systems and organisms to develop or make products

• The study of human anatomy

• The use of chemicals to treat diseases

Biotechnology companies are grouped into four categories based on the products they make and sell. Name the four categories of products.

• Pharmaceuticals, Agriculture, Industrial, Environmental

• Electronics, Clothing, Food, Furniture

• Automobiles, Construction, Textiles, Mining

• Education, Sports, Music, Art

What is the function of restriction enzymes in biotechnology?

• To paste pieces of DNA together

• To cut DNA at specific nucleotide sequences

• To replicate DNA

• To transcribe RNA

What are genetically modified organisms (GMOs)?

• Organisms that contain DNA from another organism

• Organisms that have not been altered genetically

• Organisms that are naturally resistant to antibiotics

• Organisms that are used only in industrial processes

What is the significance of recombinant DNA in biotechnology?

• It is used to create new species of plants

• It is used to create new combinations of DNA information

• It is used to enhance the color of flowers

• It is used to increase the size of fruits

What is the purpose of transferring genes that code for certain traits from one species to another in genetically engineered plants?

• To make the plants glow
