Explain why the
possible number
of proteins is
virtually unlimited.
20 different amino acids can be arranged
in many, many different sequences, each
leading to a protein with a different shape,
and a different function.
If you had to rearrange, the letters
a, b, c and d,
how many combinations can you
make? 24 (4x3x2x1)
If each letter represented an
amino acid, what would each 4
letter combination represent?
a protein

Why DNA is important to a cell?
Be specific!
Include the following words in your answer:
DNA, enzymes, proteins, amino acids,
synthesis, information, chemical reactions
DNA has the information
for the synthesis of proteins
from amino acids. Some of
these proteins are enzymes
that control the rate of
chemical reactions in a cell.
The Flow of Genetic Information
Sequence of bases in DNA
determines the
Sequence of bases in RNA
determines the
Sequence of amino acids in Protein
Put each of the following terms in the appropriate
spot above the pH scale:
weak acid,
strong acid,
Strong acid
strong base,
Weak acid
