Slide 3
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 dont know the
answer use your notes or HEYflip the page over
Slide 4
Where does the process of Translation occur in the cell?
Slide 5
Answer: The process of translation occurs in the ribosome of
the cell.
Slide 6
Name the process in which mRNA is made and where it
occurs.
Slide 7
Answer: Transcription Occurs in the nucleus of the cell.
Slide 8
What are the four nitrogenous bases found in RNA?
Slide 9
Answer: Adenine, Uracil, Cytosine, Guanine
Slide 10
Would you see the following sequence in DNA or RNA? Why? ACC
GGC CAC GCG AAC AGA UAG GGC CAG
Slide 11
Answer: RNA The sequence contains uracil at the 7 th codon
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
Slide 17
Answer: Yes a point mutation (substitution of a base) has
occurred at the fourth codon.
Slide 18
What is a codon and what does it do?
Slide 19
Answer: A 3 nucleotide sequence of mRNA that tells tRNA what
amino acid to bring to the ribosome
Slide 20
GET YOUR CODE ON!! What amino acids will be obtained from the
following codons: AUG CAG UUU GGC
Slide 21
Answer: AUG will give you methionine CAG will give you
glutamine UUU will give you phenylalanine GGC will give you
glycine
Slide 22
What is a polypeptide?
Slide 23
Answer: The polymer of a protein. It is composed of many amino
acids linked together.
Slide 24
What is a mutation?
Slide 25
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
Slide 26
What are the monomers for a carbohydrate, lipid, and protein.
Which one contains Nitrogen?
Slide 27
Answer: The monomer of a______ is a _________ Carbohydrate
Monosaccharide Lipid Fatty Acid Protein Amino Acid Only the Protein
contains Nitrogen (N).
Slide 28
Where are proteins produced in the cell?
Slide 29
Answer: In the ribosome
Slide 30
How many different substrates can fit with one enzyme?
Slide 31
Answer: Only one. They are very specific.
Slide 32
What is a cell membrane mainly composed of? (its a
bio-molecule)
Slide 33
Answer: The cell membrane is mostly composed (made up of)
LIPIDS
Slide 34
How is a prokaryotic cell different from a eukaryotic
cell?
Slide 35
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.
Slide 36
Give one example of a prokaryotic organism.
Slide 37
Answer: Bacteria
Slide 38
Give one example of a eukaryotic organism.
Slide 39
Answer: Plants, Animals, Fungi..basically any living thing is a
Eukaryotic organism except for Bacteria.
