1. True or False: A virus is considered a microorganism. False. Viruses are not living and as such

general term that includes microorganisms and viruses.
2. What is the smallest biological unit of life? A cell.
3. At a generalized level, all cells are comprised of what? Macromolecules* *A student may also
answer: Proteins, Lipids, Nucleic acids and Polysaccharides but they must answer with all
four to be fully correct.
1. How many different types of amino acids are available from which to make proteins? 20
2. Define an essential amino acid. An essential amino acid cannot be produced by the human
body and as such must be take in from the environment through alternative sources (i.e)
food.

2. Where can the two major types of nucleic acids be found in the cell and what are their roles?
co
While both DNA and RNA can be found in the nucleus (center of the cell), only RNA is capable
eH w
of leaving the nucleus. DNA contains a vast amount of hereditary information and is
o.
responsible for the inheritable characteristics of living organisms. RNA is responsible for
rs e
deciphering the hereditary information in DNA and using it to synthesize proteins.
