SUMMATIVE TEST in Biotechnology 8

1.) Which statement is correct?

A. Modern biotechnology is the use of natural organisms by humans to create or modify foods or other useful products. Examples of modern biotechnology include using yeasts for fermentation and practicing selective seed collection to create hardier crops.

B.  Traditional biotechnology is the use of natural organisms by humans to create or modify foods or other useful products. Examples of traditional biotechnology include using yeasts for fermentation and practicing selective seed collection to create hardier crops.

2.) Karl Marx is a Hungarian engineer who first coined the term ‘biotechnology’ in 1919, meaning the production of products from raw materials with the aid of living organisms.

3.) Which best describes the discovery of DNA Manipulation?

A. DNA manipulation was first applied during the time of the Egyptians through mummification.

B. DNA manipulation was discovered and applied to treat genetic disorders in modern biotechnology.
