Chapter 12 Review
Battle Royale-Style
Battle Royale Rules!
• Each person from your team will be up at the board one
time.
• Each person from your team may go up to the board to
assist someone one time. After that they may not be a
helper for the remainder of the game. No direct
communication between the group and the board.
• You must show your work with appropriate units for math
problems.
• You must write in a complete, stand-alone sentence for
explanations (IQIA).
• Lists must be written in order (answers only)
• The point will be awarded for the team with the correct,
complete answer that puts their pen down first.
• Pride for the winning team!!!
Let’s assemble teams!
Team RIGHT:
Some people
Team MIDDLE:
Some other people
Team LEFT:
The remaining people
Let’s assemble teams!

You must answer in a complete
sentence!
1. Write three complete sentences contrasting DNA
and RNA. Each sentence must have information
about each nucleic acid.
Example: Mrs. Tucker has lots and lots of friends, whereas Mr.
Stephens has few/no friends.
Sugar (ribose/deoxyribose); bases
(thymine/uracil); single vs. double
stranded; one type vs. three types
Reorder and rewrite!
2. Rearrange and rewrite the major events of
transcription and translation in the order that
they occur.
•
•
•
•
•
•
The complete polypeptide is released.
Messenger RNA is transcribed from DNA
Amino acids are joined until a stop codon is reached.
mRNA leaves the nucleus
tRNA brings methionine to the start codon
mRNA goes to ribosome

3. Write three complete sentences contrasting
DNA replication and transcription. Each
sentence must have information about each
process.
Example: Mrs. Goodnight lets her bio students use notecards
on tests, whereas Mr. Stephens does not.
Enzymes used; types of nucleotides added; final
product
You must answer in a complete
sentence!
4. What are the three types of RNA and their
functions? (Abbreviations are allowed)
mRNA = carries message from DNA to
ribosome
rRNA = part of ribosome, helps make proteins
tRNA = carries amino acids to ribosome,
converts mRNA into protein
SHOW YOUR WORK!
5. Transcribe and translate the following DNA
template:
TACGGACCCCTTTAAATGCTGGTTGACACT
AUGCCUGGGGAAAUUUACGACCAACUGUGA
MET PRO GLY GLU ISO TYR ASP GLN LEU STOP
NO NEED for complete sentences!
6. Use the following DNA sequence to show
examples of the three gene mutations. Write
the mutated sequence, circle the mutation and
label the mutation type. You should end up
with three separate DNA sequences.
TA C G G A C C C
substitution, deletion, insertion
You must answer in a complete
sentence!
7. Write one or two sentences that relate the
following vocabulary terms: TATA box,
promoter, RNA polymerase, gene,
transcription. Please underline each
vocabulary word used.
A TATA box helps RNA polymerase bind to
the promoter of a gene during
transcription.
You must make a pretty picture!
8. Draw a picture of DNA molecule that is three
nucleotides long. Label the parts of one
nucleotide, show appropriate base-paring
rules and label the hydrogen bond(s).
You must answer in a complete
sentence!
9.0 Write a few sentences that relate the
following vocabulary terms—codon; anticodon;
tRNA; mRNA; nucleotide; amino acid;
polypeptide. Please underline each vocabulary
word used.
• Three nucleotides on mRNA is a codon,
which are complementary to anticodons on
tRNA. Each tRNA molecule carries a specific
amino acid, which are joined by bonds to
form a polypeptide chain.
Complete sentence!
10. What is the basic function of hox genes?
• Body plan in multicellular organisms.
