UNIT 7
Review Questions
1. How is bioengineering different from biology?
Biology and bioengineering could be considered similar but in reality they are different
one from another. They are linked as biology builds it’s research on top of
bioengineering creations.
2. Explain the separation and purification process.
The separation and purification process is designed to make substances pure, it
consists of breaking apart and building back substances in order to make them free of
any impurities
3. Why are bioengineers interested in viruses?
Bioengineers are interested in viruses because of the potential they have, they can be
genetically modified in order to make them target special cells such as bacterias, and
to reduce human diseases and suffering, or just weaponize them and make them more
deadly than before.
4. How do viruses reproduce?
Viruses don’t reproduce by themself, they trick cells into duplicating the viruses, this
process will continue and viruses will keep being produced until the cell dies.
5. Why are viruses so difficult to combat?
Their method of reproduction is the factor that makes them difficult to combat, for the
moment we didn’t find a way to make the difference between the infected and the
non-infected cells, and we can’t just destroy them all. It would cause the death of the
infected.
Critical Thinking Questions
1. How do you think that prokaryotic cells are limited since they do not have a
nucleus? How does this make their function different from cells that have a
nucleus?
The prokaryotic cells have a limited DNA since they do not have a nucleus. They
are limited in size and reproduce only byu division. They are simple organisms.
Since they don’t have a nucleus they can’t combine to form larger organisms.
