Extra Credit
(up to 4
points!)

C LAYER Complete (70-74 points): _________
B LAYER- Apply knowledge to a new situation (assignments are graded with points)
points
received
Assignment (10 points possible)
STEP 5
IN CLASS ONLY
You may use
your binder.
DNA Structure & Protein Synthesis QUIZ
 1. On a large sheet of paper, draw the outline of a cell (a large circle is fine!)
 2. Draw & label the organelle that contains DNA – make it fairly large (1 point)
 3. Draw & label the organelle where protein synthesis will take place (1 point)
 4. Within the appropriate organelle, draw a simple double helix model of DNA
using letters to represent 12 base pairs on each strand (you create a UNIQUE
order of the base pairs) (2 points)
 5. Highlight the strand of DNA that will be transcribed
 6. On the organelle where protein synthesis will take place, draw a squiggle
line to represent the mRNA strand that is transcribed from the DNA strand you
highlighted (include the appropriate letters to represent each base on the
mRNA) (1 point)
 7. Draw parenthesis around each CODON on the mRNA strand (1 point)
 8. Next to the codons, draw & LABEL circles to represent the specific amino
acids that will be translated from the mRNA – hint, you will need to use the
codon chart (2 points)
 9. At the bottom of your paper, re-write the DNA sequence of the original
strand you highlighted WITH a mutation in the DNA & label the type of
mutation (2 points)
 10. Extra credit: Trancribe & translate the mutated DNA (2 points)
B LAYER Complete (record C layer + B Layer points): _________
(must complete B layer before receiving credit for the A layer)
A LAYER- Critical analysis (assignments are graded with points)
points
received
Assignment (16 points possible)
STEP 6
DNA Concept Map
 Create a concept map using as many of these words as possible: James Watson,
Francis Crick, chromosome, DNA, double helix, nucleotide, nitrogen base,
phosphate group, deoxyribose, helicase, RNA polymerase, nucleus, gene, RNA,
mRNA, ribosome, transcription, translation, codon, anticodon, tRNA, amino acid,
polypeptide, protein
 Points will be awarded based on:
o # of words correctly used: up to 5 points
o Clarity of connections between topics (may include words on the lines
between each concept “bubble” if needede): up to 6 points
o Organization, use of color, neatness: up to 5 points
Rosalind Franklin
 Who was SHE? What was her role in the discovery of the structure of DNA?
Why wasn’t she awarded the nobel prize?
