Q & A

What is the definition of biotechnology according to the United Nations?

Biotechnology refers to any technological application that uses biological systems and living organisms to modify or produce products or processes for specific uses.

What marked the beginning of biotechnology in history?

The earliest use of biotechnology dates back to 10,000 - 2,000 BCE with the production of alcoholic beverages and bread using fermentation by the Sumerians and Babylonians.

Who first discovered the role of microorganisms in fermentation?

In 1805, scientists using microscopes were able to observe microorganisms, which were later confirmed by Louis Pasteur in 1875 as responsible for fermentation.

What important discovery did Alexander Fleming make in 1928?

Alexander Fleming discovered penicillin by observing that a fungus (Penicillium) inhibited bacterial growth, leading to the development of antibiotics.

What contribution did Oswald Avery make in 1943?

Oswald Avery discovered that DNA carries genetic information, establishing the fundamental role of DNA in genetics.

What significant discovery about DNA was made in 1953?

In 1953, James Watson and Francis Crick described the double-helix structure of DNA, which revolutionized the understanding of genetics.

What was the first genetically modified plant, and when was it created?

The first genetically modified plant was a tobacco plant, created in 1983.

What is the significance of the cloning of Dolly the sheep in 1997?

The cloning of Dolly the sheep in 1997 was the first successful cloning of a mammal, marking a milestone in biotechnology and genetic research.

What role did biotechnology play in the fight against COVID-19?

Biotechnology played a crucial role in the development of COVID-19 vaccines and other medical treatments, helping to combat the global pandemic.

What are the different colors of biotechnology, and what do they represent?

Biotechnology is categorized by colors to represent different areas: Yellow (Food and Nutrition), Red (Medical and Pharmaceutical), Green (Agriculture), White (Industrial), Gray (Environmental), Blue (Marine), and Golden (Informatics). Each color represents a unique application in the field.
