What are the four main types of macromolecules found in a cell?
CORRECT ANSWER:
Proteins, Lipids, Nucleic Acids and Carbohydrates
How many different types of amino acids are available to make
proteins?
CORRECT ANSWER:
20
,How many amino acids are classified as being essential amino
acids?
CORRECT ANSWER:
9
Where can the two major types of nucleic acids be found in the cell
and what are their roles?
CORRECT ANSWER:
DNA and RNA
They are both found in the nucleus. DNA contains and stores
hereditary information and is responsible for the characteristics of
living organisms. RNA is a messenger and responsible for
translating the hereditary information in DNA and synthesizes
proteins.
