The Emerald City Review
1. Use this sheet to draw a typical plant cell. Trace the following path in the cell 1)
mRNA being made from DNA, 2) proteins being made from mRNA, 3) proteins
being packaged into vesicles, 4) vesicles being released into the cytoplasm, and 5)
proteins being degraded after no longer needed in the cell. Circle the organelle
responsible for producing sugar in the plant cell.

Cell of Ozland
Welcome to Oz! As you begin your journey into the eukaryotic cell, be certain to
stay on the Yellow Microtubule Road as you move from organelle to organelle.
When your teacher allows you to enter the cell be careful as you move across the
plasma membrane and enter the nucleus.
Station 1: Nucleus
1. Grab a DNA badge on the back of a chair in the nucleus. One important process that
takes place in the nucleus is transcription. Transcribe the following DNA sequence into
mRNA :
DNA:
TACGATCCGGCAATC
RNA:
A U G _______________________
2. After you transcribe your DNA, you are ready to move onto the Endoplasmic Reticulum.
Station 2: Endoplasmic Reticulum (ER)
1. Sit down at the Endoplasmic Reticulum. Notice that this piece of ER has
ribosomes on it. So, this is (circle one:
( rough / smooth ) ER.
2. Use a codon chart to translate the mRNA you made into amino acids. For
example, the first codon is AUG and produces methionine.
_________________________________________________________________________________________________
_________________________________________________________________________________________________
_________________________________________________________________________________________________
3. After you have translated your mRNA into amino acids, make your protein. Represent
each amino acid by a particular color pipe cleaner. Feel free to bend, twist, and coil
your amino acids. Your newly synthesized protein should have 5 different colors, each
corresponding to each amino acid you translated. After your protein is made, go onto
the Golgi apparatus.
Station 3. Golgi Apparatus
1. Grab a small vesicle (sandwich bag) from the cis face and take a seat in the Golgi.
2. Package your protein into the vesicle. Be sure to place three phosphate groups in your
vesicle before moving on to the mitochondria.
3. The protein that you made can act as a channel that will allow you to enter the
mitochondria of the cell.
Station 4. Mitochondria
1. Follow the worksheet to make a pinwheel.
2. After making the pinwheel, blow on it and produce some wind energy.
3. The main job of the mitochondria is to produce energy for the cell.
4. After this, feel free to take your energy machine with you and throw away your vesicle
into the lysosome for degradation.
5. If you haven’t done so, visit the hydrophobic vs. hydrophilic station as well as the
protein structure station.
