Which pairing correctly matches a biotechnology application with its use?
- A.Rosie transgenic cow — production of human insulin in its milk
- B.Transgenic mice — study of the biological role of genes and development of disease modelsCorrect answer
- C.Golden rice — production of a bacterial toxin against insect pests
- D.Recombinant hepatitis B vaccine — production of viral particles in human red blood cells
Solution
Transgenic animals, especially mice, are used to investigate gene function, understand disease mechanisms and serve as disease models. Rosie produced human alpha-lactalbumin, golden rice produces β-carotene, and recombinant hepatitis B vaccine antigen is produced using genetically engineered cells such as yeast.
