Quiz 4 Flashcards
How can transgenic plants be created (we discussed four different ways in class)?
chemical treatment, bacterial transfer, physical bombardment, electroporation
Why do human create transgenic plants (i.e. how are they useful)?
You can make them resistant to disease, frost and droughts
How can recombinant DNA help cure some diseases
replace the DNA that doesn’t allow us to produce certain proteins
How can we create needed human proteins with recombinant DNA
The gene is isolated and cloned into an expression vector
How can recombinant DNA help cure some diseases (know the examples discussed in class)?
Diabetes can be cured by inserting recombinant DNA that allows our body signals to start producing insulin
How can we create missing proteins within the human body with recombinant DNA (know the examples discussed in class)?
repair damaged tissue in some way
There is growing evidence that stem cell therapy has the potential to treat a variety of chronic diseases. However, which statement describe one of the current problems with using this technology?
it takes 10 years and a billion dollars to bring one new medicine to the market, patient recruitment is very difficult, regulatory agency oversight is extensive, public perception
___________ are fuels derived from biomass made from recently fixed carbon sources, as opposed to fuels derived from fossil fuels.
bio fuels
What part of the algae are you using to create biofuels?
lipids, fats
Why is genetically engineered microalgae better than using regularly grown algae for biofuel production
it is tiny and produces 50% more in lipids
How can algae biofuel production lead to cogeneration systems being implemented (i.e. why are they are green energy source monetarily and figuratively)?
feed C02 to the photobioreactor, which makes bio fuels for bio gasses that ultimately powers your factory
What is the one main problem, currently, with trying to produce biofuels?
it costs a lot of money
The degradation or metabolism of hydrocarbons pollutants by microorganisms is called _____________.
Bioremediation
What affects the degradation rates of hydrocarbons by microorganisms?
the environment (temperature, oxygen available, ph available, other micro-organisms present, are there enough nutrients)
What is the one main problem, currently, with trying to use large quantities of microorganisms to degrade hydrocarbons in the environment?
its extremely slow
