1. This is a model of a cell using materials: plastic bag, stryofoam ball, a marble, yellow, blue, red and green clay, steel wool, macaroni noodles, raisins, the candy dots, candy peanut, rubber bands, and straws.
2. This is the nucleus (styrofoam ball) molded with yellow clay for the nuclear membrane and inserted with a marble to represent the nucleolus. The plastic bag is the cell membrane. The nucleus is the storage site for genetic information. The cell membrane protects the cell and allows particular substances inside and outside the cell.
3. This is the rough (steel wool) and smooth (elbow macaroni) endoplasmic reticulum. The rough endoplasmic reticulum, which is studded with ribosomes, is the location for protein synthesis.
4. This is the ribosmoes (red clay balls) and the vesicles (raisins). The ribosomes assist in protein synthesis on the rough endoplasmic reticulum. The vesicles break down cell substances.
5. This is the lysosomes (the candy dots) and the mitochondria (candy peanut). The lysosomes takes the proteins and lipids from the endoplasmic reticulum and transports them to the golgi apparatus. The mitochondria is the powerhouse of the cell, because energy conversion, called cellular respiration, occurs.
6. This is the golgi apparatus (rubber bands) and the cilia (bundle of straws). The golgi apparatus further modifies the proteins and lipids brought by the lysosomes. The cilia allow parts of the cell to move, allowing processes occur and continue.
7. This is the beginning of the model of my cell. There is the cell membrane, the cell's foundation, and the nucleus containing the nucleolus.
8. This is the finished model of the cell containing the nucleus, the rough and smooth endoplasmic reticulum, the ribosomes, the lysosomes, the golgi apparatus, the vesicles, the mitochondria, and the cilia.
9. This is a model of mitosis using the materials: red, green, and yellow clay, rubber bands, and the candy dots. This is the first stage, prophase, where the chromosomes ( red and yellow clay) and spindles (rubber bands and the candy dots) begin to form.
10. This is the second stage, metaphae, where the spindles line the chromosomes along the center of the nucleus.
11. This is the third stage, anaphase, where the spindles pull the chromosomes apart a pull them towards opposite ends of the nucleus.
12. This is the last stage, telophase, where the chromosomes start to turn back into chromatid as the spindles disappear. The cell splits and two identical cells are formed.
13. This is a model of DNA replication using the materials: green floral wire and twist ties. This is the DNA strand (green floral wire) and the complementary base pairs (twist ties) holding the two strands together. In DNA replication, part of the strand unzips and allows for a new strand to be copied and made from the old strand.
14. This is a model of transcription using the materials: green and black floral wire and sour gummy worms. This is the DNA strand (green floral wire) with its complementary base pairs (sour gummy worms) and an RNA strand (black floral wire) with its base pairs (sour gummy worms). In the process transcription, the DNA strand is broken apart in order for the RNA strand to connect to it with its complementary base pairs and create the messenger RNA.
15. This is a model of translation using the materials: black floral wire, green and yellow clay, sour gummy worms, and the candy dots. This is the messenger RNA strand (black floral wire) the base pairs (sour gummy worms), the ribosome (yellow clay), the transfer RNA, which is a molecule that transports proteins by long protein chains (green clay) ,and the proteins ( the candy dots). In the process translation, the mRNA binds to the ribosome along with the tRNA.
16. This is the ribosome moving along the mRNA, three base pairs at a time.
17. This is where each base pair initiates what proteins shall be made and the proteins are added to the long protein chain connected to the tRNA.
18. This is where the process ends when one of the proteins says "stop." The mRNA and tRNA release from the ribosome and complete protein synthesis.

Laurel, what a lot of great talents you bring to your blog. Almost 100% perfect—I would like to see you master integrating your outline, text and images for the compendiums as some folks have. But really your ability to show your comprehension of the biology and apply it is impressive—keep it up!

SELF/UNIT EVALUATION: Thanks for the very honest self-evaluation and nice feedback on the unit. I appreciate your feedback on the logistics of the course and how the unit went for you. I’m also glad you’re retaining a lot and too bad about that first quiz. If you keep on working hard, I’m sure it won’t affect your final grade.
COMPENDIUM REVIEW 1: CELLS: Exemplary review—everything I say for comp rev 2 applies. Keep it up!
COMPENDIUM REVIEW 2: GENETICS: this is an exemplary review. I like the images you chose. I like how you organized your outline. I like all the text you wrote and how you cited different sources. My only request, given all your obvious talents, is that you figure out how to put outline, text and images all together! But obvious all the biology is in place—just mastering the computer should be easy!!
MICROSCOPE LAB: Great exemplary job. Everything I say for Dragon lab applies.
DRAGON GENETICS: Exemplary lab write-up. You got the images, explained them well, put it all in context cited your references. And I really like the personal perspective on genetics and the extra bonus images! Wow—way to go—nailed this one!.
BUILD A CELL: the model is stunning and beautiful and incredibly complete. Well-presented. The only thing you might have done is a bit of an introduction or conclusion on the whole workings of a cell—just a paragraph explaining what everything does. But really exemplary work! Oops—I didn’t see the next entry—that makes it perfect!
ETHICAL ISSUE ESSAY: GENETIC ENGINEERING. Great job on the essay. Interesting writing, good approach to the issue and you give different viewpoints a fair chance.
Please don’t forget to do your peer color group feedback on their ethical issues essays—you’ll probably find it interesting to see some other blogs also. And get started on Unit II if you haven’t already. Let me know if you have any questions or concerns about this feedback or your grades which can be seen on the YC Blackboard site.
