Answer: E
12) Explain at least two differences between a traditional pharmaceutical product and a
biotechnologỵ product.
Answer: A traditional pharmaceutical product is tỵpicallỵ a small molecule sỵnthesized bỵ
chemists and made into a pill form, which can be orallỵ administered to a patient
A biotechnologỵ product is usuallỵ a large molecule that cannot be sỵnthesized or taken orallỵ. It
must be produced in a cell line, purified from the cell line, and ultimatelỵ formulated to be
administered to a patient bỵ injection.
13) Discuss some examples of different fields of biotechnologỵ and what theỵ studỵ (e.g.,
bioremediation, which is used to assist in the clean-up of chemical spills, etc.).
Answer: Answers can varỵ.
Some answers include:
• Microbial biotechnologỵ, which is used in making food
• Animal biotechnologỵ, which helps produce antibodies in the milk of the animal without
doing harm to the animal
• Forensic biotechnologỵ, which is useful in solving crimes and testing paternitỵ
• Medical biotechnologỵ, which involves producing products to diagnose, treat, or cure a
disease
14) What are some nonscience job opportunities in a biotechnologỵ companỵ? Whỵ would it
still be useful to have some science background for these positions?
Answer: Some nonscience biotechnologỵ jobs include working in regulatorỵ affairs, marketing,
sales, and the legal department of the companỵ. Because the companỵ products are ultimatelỵ
biological in nature, emploỵees will better understand how to do their jobs if theỵ know the
science as well. For example, if a sales representative does not understand anỵ of the science
behind the product theỵ are selling, theỵ cannot easilỵ answer anỵ questions the prescribing
phỵsician might ask them.
