1.You are a world famous scientist who has discovered the gene that codes for a specific protein used to dissolve blood clots in humans. You are about to mass produce this gene for medical science. What must you know about this specific protein in order to begin gene production?
A) the mRNA anticodons
B) the shape of the protein molecule
C) the amino acid sequence of the protein
D) the nucleotide sequence of the human genome
2.Spermatogenesis produces __________________ from one original cell.
A) two diploid cells
B) two haploid cells
C) four diploid cells
D) four haploid cells
3.As scientists have developed more productive crop varieties, farmers have switched from growing many traditional varieties to new high-yield varieties. For example, in Peru, there are about 500 native varieties of potatoes that Indians once grew. This has been reduced to about 20 genetically improved potato varieties worldwide. Besides the number of varieties of potatoes being reduced, what else is reduced by this practice?
A) the potato gene pool
B) human dietary choices
C) types of soil nutrients
D) food chains that include potatoes
4.All of the following EXCEPT the resistance of _________ demonstrate artificially selected resistance.
A) beef cattle, to "shipping fever",
B) many agricultural wheat varieties, to drought and fungus,
C) Anatarctic fish to freezing, due to antifreeze proteins in their blood,
D) many common grasshopper species to pesticides, such as diazinon, sevin, and others,
