Exemplary flashcards for Biotechnology SS 2020 at the Hochschule Bonn-Rhein-Sieg on StudySmarter:

Biotechnology SS 2020

What is selective breeding?

Purposely mating of animals with desirable features
→ Selection of spontaneous mutations

Biotechnology SS 2020

What is traditional biotechnology?

Generation of new varieties of crop plants and livestock by retaining desirable traits of wild species with more beneficial traits for humans 

Biotechnology SS 2020

In traditional biotechnology, which aims wanted to be reached regarding plant selection?

  • Higher yield
  • More/Bigger seeds
  • Higher nutritional value
  • Better taste
  • Better properties in harvest/transport/storage

Biotechnology SS 2020

In traditional biotechnology, which aims wanted to be reached regarding animal domestication and breeding?

Benefits for humans
→ Specific morphology of dogs

Not necessarily beneficial for the animal, for example breeding large turkeys give a lot of meat but they do not live a happy life

Biotechnology SS 2020

Which food products have already been produced in traditional biotechnology?

  • Wine
  • Bread
  • Cheese
  • Tofu
  • Soy sauce

    Fermentations

Biotechnology SS 2020

What is retting?

Retting is a traditional biotechnological technique to produce ship ropes out of cellulose fibers from rotten composable materials

Biotechnology SS 2020

What is biotechnology? Give a general definition.

Biotechnology uses biological organisms, systems or processes to manufacturing and service industries 

Biotechnology SS 2020

Name the three major areas of activity in biotechnology.

  • Health/Medicine
  • Agrobiotechnology
  • Industrial Biotechnology

Biotechnology SS 2020

How is biotechnology applied in health/medicine?

  • Development of therapeutics and/or diagnostics for medicine 
  • Drug delivery
  • Tissue replacement

Biotechnology SS 2020

How is biotechnology applied in agrobiotechnology?

  • (Non-)Genetically modified plants, animals and microorganisms 
  • Using biotechnological procedures in agriculture, forestry or environment
    Sensors for pollutants
    Detoxification of contaminated soil (e.g.
         with heavy metals)

Biotechnology SS 2020

What are the advantages of biotechnology versus chemical synthesis?

  • Complex molecules, like proteins, cannot be produced by chemical means
    → Or to high, unefficient price
  • Bioconversions give higher yields
    → Living organisms are optimized to use substrate efficiently (99.9% or more turnover)
  • Biological systems work under moderate conditions (room temperature, neutral pH etc)
  • Great specificity of a catalytic reaction
    Example: Exclusive production of an isomeric compound 

Biotechnology SS 2020

Can you name an example of production for which biotechnology offers great advantages compared to chemical synthesis?

Fertilizer (e.g. ammonium) is produced by the Haber-Bosch procedure
→ needs 600 °C temperature and 400 bar pressure

Nitrogenase does the same under normal growth conditions
