TEST REVIEW RULES
 Pull out a few sheets of paper or a notebook
 You will be grouped by tables for this activity
 Your table will rotate to a new table every three
minutes. (table one moves to table two, table two
moves to table three, table seven moves to table one and
so on)
 While at your station your challenge will be to write
down and try to answer as many of the questions as
possible with your group before time is up.
 If you don’t know the answer use your notes or
HEY…flip the page over 
Where does the
process of
Translation occur in
the cell?
Answer:
The process of translation
occurs in the ribosome of the
cell.
Name the process in
which mRNA is
made and where it
occurs.
Answer:
Transcription
Occurs in the nucleus
of the cell.
What are the four
nitrogenous bases
found in RNA?
Answer:
Adenine, Uracil,
Cytosine, Guanine
Would you see the
following sequence in
DNA or RNA? Why?
 ACC GGC CAC GCG AAC AGA UAG GGC CAG
Answer:
RNA
The sequence contains
uracil at the
th
7
codon
What is the sugar
found in the RNA
nucleotide?
Answer:
Ribose
Which
nitrogenous bases
pair together in
RNA?
Answer:
Adenine
 Thymine
Cytosine
Uracil
Adenine
Guanine
Examine the two mRNA
sequences. Has a mutation
occured? How do you know?
 AUG CGA GGG CUA AAA CAG UAC
 AUG CGA GGG CCA AAA CAG UAC
Answer:
Yes a point mutation (substitution
of a base) has occurred at the
fourth codon.
What is a codon
and what does it
do?
Answer:
A 3 nucleotide sequence of
mRNA that “tells” tRNA what
amino acid to bring to the
ribosome
GET YOUR CODE ON!!
What amino
acids will be
obtained from
the following
codons:
AUG
CAG
UUU
GGC
Answer:
 AUG will give you methionine
 CAG will give you glutamine
 UUU will give you phenylalanine
 GGC will give you glycine
What is a
polypeptide?
Answer:
The polymer of a protein. It
is composed of many amino
acids linked together.
What is a mutation?
Answer:
A mutation is a change in
genetic material that results
from a mistake in the
replication process
Can also be caused by
environmental factors
What are the monomers for a
carbohydrate, lipid, and
protein.
Which one contains Nitrogen?
Answer:
 The monomer of a______ is a _________
 Carbohydrate
 Lipid
 Protein
Monosaccharide
Fatty Acid
Amino Acid
 Only the Protein contains Nitrogen (N).
Where are
proteins produced
in the cell?

Answer:
In the ribosome
How many different
substrates can fit
with one enzyme?
Answer:
Only one. They are very specific.
What is a cell
membrane mainly
composed of?
(it’s a bio-molecule)
Answer:
The cell membrane is mostly
composed (made up of)
LIPIDS
How is a prokaryotic
cell different from a
eukaryotic cell?
Answer:
 Prokaryotic cells do not contain a
nucleus or membrane bound
organelles.
 They carry their DNA in the cytoplasm
while Eukaryotic cells carry their DNA
in the nucleus.
Give one example
of a prokaryotic
organism.
Answer:
Bacteria
Give one example
of a eukaryotic
organism.
Answer:
 Plants, Animals, Fungi…..basically any
living thing is a Eukaryotic organism
except for Bacteria.
