LECTURE 4

Question 1

How can transgenic plants be created?

Answer 1

electroporation, physical bombardment, chemicals treatment, bacterial transfer

Question 2

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

Answer 2

can take 10 years minimum for little research
costs over a billion dollars

Question 3

___________ are fuels derived from biomass made from recently fixed carbon sources, as opposed to fuels derived from fossil fuels. Fill in the blank.

Answer 3

biofuels

Question 4

What is the one main problem, currently, with trying to produce biofuels?

Answer 4

not cheaper than gasoline/fuel

Question 5

Why do human create transgenic plants (i.e. how are they useful)?

Answer 5

increase the resistance to disease for a plant, increase resistance to frost, make it so erbasides can’t affect it in any way, and can create it so it can withstand high drought/flood. You can also add nutrients to it.

Question 6

How can recombinant DNA help cure some diseases?

Answer 6

you can create proteins you’ve never created before

Question 7

How can we create these proteins with recombinant dna?

Answer 7

if you use recombinant dna, you can take the genes you want from one speciesia dn put it into another (create in large quantities of bacteria and put into humans)

Question 8

How can recombinant DNA help cure some diseases (know the examples discussed in class)?

Answer 8

important proteins can be produced

Question 9

What part of the algae are you using to create biofuels?

Answer 9

lipids

Question 10

How can algae biofuel production lead to cogeneration systems being implemented (i.e. why are they are green energy source monetarily and figuratively)?

Answer 10

the co2 goes through a pipe to the algae to produce algae growth

Question 11

The degradation or metabolism of hydrocarbons pollutants by microorganisms is called _____________. Fill in the blank.

Answer 11

Bioremediation

Question 12

What affects the degradation rates of hydrocarbons by microorganisms?

Answer 12

temperature
oxygen
ph
salinity
organism predator
physical +chemical
nutrient availabilty

Question 13

What is the one main problem, currently, with trying to use large quantities of microorganisms to degrade hydrocarbons in the environment?

Answer 13

takes too long to clean up

Question 14

Which statement describes a negative aspect of creating and utilizing GMOs (only know the examples discussed in class)

Answer 14

harm to human or animal health

Question 15

Why are genetically engineered plant and animals becoming very popular within the agricultural industry?

Answer 15

theyre cheaper and better for farmers
