True/False. A virus is considered a microorganism. - (answer)False: Viruses are not living and as such are
not considered microorganisms. Viruses can, however, be classified as microbes, a more general term
that includes microorganisms and viruses.
What is the smallest biological unit of life? - (answer)a cell
What are the four main types of macromolecules found in cells? - (answer)Proteins, Lipids, Nucleic
Acids, Carbohydrates
How many different types of amino acids are available from which to make proteins? - (answer)20
How many amino acids are classified as being essential amino acids? - (answer)9
Where can the two major types of nucleic acids be found in the cell, and what are their roles? -
(answer)While both DNA and RNA can be found in the nucleus (center of the cell), only RNA is capable of
leaving the nucleus. DNA contains a vast amount of hereditary information and is responsible for the
inheritable characteristics of living organisms. RNA is responsible for deciphering the hereditary
information in DNA and using it to synthesize proteins.
