Question 1
A DNA microarray (also called a DNA chip) can be used to ________.
◦ assay protein output from a genomic database
◦ mutate genes of interest
◦ trap genes that are both active and inactive
◦ scan a population of nucleic acids for abundance and mutations
◦ isolate genes from eukaryotic cell nuclei
Question 2
Many instances involving genetically modified organisms, especially food crops, will be entering the human food chain in the years to come. On what basis are genetically modified foods considered safe to eat?
◦ They are only slightly toxic.
◦ Genetically modified food products are considered safe if they are found to be not toxic or allergenic or have other negative physiological effects.
◦ All products to be cleared for human consumption have been personally tested by all members of the regulatory agency.
◦ Each genetically modified food product is screened for its resistance to antibiotics.
◦ Because of the possible economic impact of rigorous testing, such food products are minimally tested in sheep and cattle.
