Mutations
Phenotype
How can the use of transgenic crops help meet the world's demand for food?
by increasing crop production, making more nutritious foods, by making foods that don't go bad as quickly
Which of the following topics might a student studying biotechnology study?
(electrical engineering, astronomy, agriculture)
agriculture
How does it benefit the environment if a country can produce enough food to feed its own people and not have to import food?
-less use of fossil fuels to ship food from other countries
-less use of fossil fuels and other resources to distribute the food once in the country
How do biotechnology researchers create a corn plant that contains more protein?
by altering the DNA of the corn plant
What do we call the alleles that code for a particular trait?
Genotype
Genetic engineering has directly increased productivity in which US industry?
(agriculture, automobile manufacturing, media)
Agriculture
How can advances in gene therapy improve the lives of those with certain inherited diseases like Sickle Cell Anemia?
They can edit the patients genes so they no longer have symptoms of the disease.
What organisms are used to create synthetic insulin for diabetic patients?
How are bacterial cells able to produce insulin for the treatment of diabetes in humans?
The bacteria have been genetically altered to contain the DNA needed produce insulin.
Describe this genotype:
BB
homozygous dominant
How does biotechnology most benefit the economy of a state?
(creating hybrid plants, creating transgenic species, creating jobs, creating medicines)
creating jobs
(pharmaceutical salesman, pharmaceutical technician, pharmacist)
pharmaceutical technician
What are the three possible effects of a mutation?
beneficial, harmful, neutral
By what process are pure-bred dogs produced?
selective breeding/artificial selection
Describe this genotype:
Bb
heterozygous
What is most likely the greatest economic benefit from biotechnology?
(improved DNA testing for crimes, fewer people needing insulin, increased disease-resistant crops with greater yield)
increased disease-resistant crops with greater yield
A company that creates hair dye would most likely employ a biotechnician to:
(research trends, develop new colors, test the safety of products, create attractive packaging)
What could happen if a mutation changes a nucleotide base in a codon?
The codon could cause the cell to make a different protein.
Or
Mutation
How did farmers first probably use biotechnology (before scientists knew about DNA, etc) to produce better crops and livestock?
selective breeding/artificial selection
Complete a Punnett square; list the possible genotypes and phenotypes.

aa 1/4 25%
How is increased yield a positive result of biotechnology in agriculture?
Farmers are able to grow more crops on the same amount of land.
How does knowledge about human genetics best help patients?
(Doctors can remove damaged genes, Doctors can change sick patient's genes, Doctors can predict who is at risk to develop a genetic disease.)
Doctors can predict who is at risk to develop a genetic disease.
How could you know if a food product contained genetically modified ingredients?
You might not be able to!!
