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

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 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 could happen if a mutation changes a nucleotide base in a codon?
The codon could cause the cell to make a different protein.
Or
